Abstract:
A vehicular behavior controller is disclosed. The controller comprises a turning force application mechanism and a stabilization controller. The turning force application mechanism applies a turning force to a vehicle. The stabilization controller is operable to regulate the turning force application mechanism in such a manner that a turning characteristic and a straight travel property of the vehicle are stabilized while in an unstable velocity area when the velocity of the vehicle exceeds a stable limit velocity.
Abstract:
An internal-combustion engine is disclosed in which a pair of inlet valves and a pair of outlet valves are provided within the combustion chamber formed in each of a row of cylinders. A first ignition plug is disposed in the cylinder head within a central area of the combustion chamber in plan view. Second and third ignition plugs are disposed in the cylinder head at opposite peripheral portions of the combustion chamber positioned approximately along the first axis direction in plan view, the second and third ignition plugs are arranged so that the discharge electrode portions of the second and third ignition plugs being inclined inwardly of the combustion chamber in opposite directions and are substantially symmetrical relative with the first ignition plug in plan view. A line intersecting the discharge electrode portions of the second and third ignition plugs forms an oblique angle with the direction of the row of cylinders in plan view.
Abstract:
The adhesiveness of a thermal spray coating and a cylinder internal surface is improved by forming a sufficient roughened surface on an internal surface. A processing roller is installed on the main shaft of a processing device via a pressurizing mechanism. An uneven surface is provided on the external periphery of the processing roller. By pressing the processing roller against the internal surface while the roller rotates and moves, a fine unevenness that corresponds to the unevenness of the roller is formed on the cylinder internal surface. A thermal spray coating is formed on the internal surface where the inner surface has been roughened by forming the above-mentioned unevenness.
Abstract:
A proactive pedal algorithm is used to modify an accelerator pedal map to ensure the deceleration when the accelerator pedal is released matches driver expectation. Modifying the accelerator pedal map provides the driver of a vehicle the sensation that the vehicle resists moving when travelling in dense scenes with potentially high deceleration requirements and coasts easily in scenes with low deceleration requirements. The accelerator pedal map is modified based on a scene determination to classify other remote vehicles as in-lane, neighbor-lane, or on-coming.
Abstract:
Route planning in automated driving of an autonomous vehicle includes obtaining an indication that a standard definition map is to be used in addition to a high definition map for obtaining a route; obtaining the route for automatically driving a vehicle to a destination, where the route includes a road of the standard definition map; obtaining a policy from a safety decision component, where the policy provides actions for states the road, and the actions constrain a trajectory of the autonomous vehicle along the road; receiving the actions from the safety decision component; and autonomously traversing the road according to the actions
Abstract:
A method for contingency planning for an autonomous vehicle (AV) includes determining a nominal trajectory for the AV; detecting a hazard object that does not intrude into a path of the AV at a time of the detecting the hazard object; determining a hazard zone for the hazard object; determining a time of arrival of the AV at the hazard zone; determining a contingency trajectory for the AV; controlling the AV according to the contingency trajectory; and, in response to the hazard object intruding into the path of the AV, controlling the AV to perform a maneuver to avoid the hazard object. The contingency trajectory includes at least one of a lateral contingency or a longitudinal contingency. The contingency trajectory is determined using the time of arrival of the AV at the hazard zone.
Abstract:
Traversing, by an autonomous vehicle, a vehicle transportation network, may include identifying a distinct vehicle operational scenario, wherein traversing the vehicle transportation network includes traversing a portion of the vehicle transportation network that includes the distinct vehicle operational scenario, communicating shared scenario-specific operational control management data associated with the distinct vehicle operational scenario with an external shared scenario-specific operational control management system, operating a scenario-specific operational control evaluation module instance including an instance of a scenario-specific operational control evaluation model of the distinct vehicle operational scenario, and wherein operating the scenario-specific operational control evaluation module instance includes identifying a policy for the scenario-specific operational control evaluation model, receiving a candidate vehicle control action from the policy for the scenario-specific operational control evaluation model, and traversing a portion of the vehicle transportation network based on the candidate vehicle control action.
Abstract:
A vehicle front end structure (14) includes an engine cradle (26) and a force receiving structure (12). The engine cradle (26) has a front corner (50) and an engine (70) mounted to the engine cradle (26). The force receiving structure (12) has a force receiving surface (134) extending laterally outboard from proximate the front comer (50) of the engine cradle (26) and a force directing section (140) located rearward of the force receiving surface (134). The force receiving structure (12) is installed to the engine cradle (26) by a vertically oriented first mechanical fastener (Fi) designed and structured such that during an impact event where an impacting force is applied to the force receiving surface (134), the force receiving structure (12) pivots about the first mechanical fastener (Fi) with an outboard portion of the force receiving surface (134) initially moving rearward relative to the engine cradle (26) and the force directing section (140) initially moving laterally inboard contacting the engine (12) and imparting a portion of the impacting force thereto.
Abstract:
Interactive external vehicle-user communication may include identifying operational environment information representing a current operational environment for an AV; identifying a target external user based on the current operational environment for the AV, the target external user is identified based on sensor information from a sensor of the AV; controlling the AV to output, for the target external user, a first semiotic representation of a control information of the AV related to the operational environment information; receiving an acknowledgement of the first semiotic representation from the target external user; and in response to the acknowledgement, controlling the AV to traverse the portion of the vehicle transportation network, such that controlling the AV to traverse the portion of the vehicle transportation network includes controlling the AV to output a second semiotic representation based on the acknowledgement from the target external user.
Abstract:
An in-module media assembly includes a display screen, a media chassis and a shock absorbing member. The display screen has an interior- facing side and a non-interior facing side. The media chassis is mounted to a lower half of the display screen and extends from the non-interior facing side of the display screen. The shock absorbing member has a screen attachment part and a contact part. The screen attachment part is attached to an upper half of the display screen and extends.from the non-interior facing side. The contact part is configured to at least one of contact the media chassis and displace relative to the media chassis upon relative movement of the upper half of the display screen towards the media chassis.
