Abstract:
In order to achieve a comfortable starting process with low wear, a braking torque, set by the driver by way of a brake pedal, an acceleration torque, requested by the driver via the accelerator pedal, and a holding torque, required for holding a motor vehicle on a gradient, are determined, and the engagement of the starting clutch, as well as the release of the service brake, are coordinated such that during the release of the service brake, the sum of the clutch torque and braking torque corresponds to the holding torque, and the clutch torque of the starting clutch is increased by the acceleration torque only when the service brake has been largely released.
Abstract:
An electromechanical parking brake system for a heavy vehicle braked by air-actuated service brakes includes an EPB-ECU and a first electromechanical parking brake actuator controlled by the EPB-ECU. The electromechanical parking brake system further includes a redundant sub-system for applying a second parking brake in an event of a failure in the EPB-ECU or the first electromechanical parking brake actuator.
Abstract:
An electronic brake system and a method for regulating the brake pressure in an electronically-controlled brake system of a motorcycle are provided. The method includes the step of actively building a brake pressure in a wheel brake circuit to prevent a motorcycle from moving. The method further includes the step of maintaining the brake pressure in the wheel brake circuit once (i) the motorcycle comes to a standstill or is at a standstill or is approximately at a standstill, and (ii) an activation condition is fulfilled.
Abstract:
An ECU executes a program including the steps of: if brake hold control is currently exerted , setting at zero a controlled value of a degree of operation of an accelerator pedal used as a controlled value of a degree of a request made by a driver for acceleration, to control a force output to drive the vehicle; if an actual value of the degree of operation of the accelerator pedal serving as an actual value of the degree of the request made by the driver for acceleration is larger than a predetermined degree, determining that there is a request from the driver for acceleration; outputting a command to cancel the brake hold control; and converging the controlled value of the degree of operation of the accelerator pedal to the actual value of the degree of operation of the accelerator pedal.
Abstract:
Following an automobile start command, at least one condition is examined before a hill start assist is executed and if the condition is fulfilled, the execution of the hill start assist is prevented.
Abstract:
A method of releasing brakes of a motor vehicle including: if no vehicle start command takes place, after manual application of the vehicle brakes in a position to immobilize the vehicle when at rest is over, an assistance device progressively releases the brakes according to a suitable control scheme configured to make the vehicle move under its own weight, generally tending towards predetermined non-zero speed and acceleration conditions, and then, when the predetermined conditions are considered to have been reached, the assistance device stops releasing the brakes.
Abstract:
There is provided a control unit including a vehicle speed sensor for detecting a vehicle speed, a vehicle stop determination module for determining whether or not a vehicle is stopping based on a detection result of the vehicle sensor and a controller, wherein the controller operates an inclination component of gravity acceleration in a longitudinal direction of the vehicle on a road surface on which the vehicle is running based on an output of the power source detected by a power source output sensor and a brake torque detected by a brake torque sensors when the stop determination unit is determining that the vehicle is in a stopped state and controls either of the output of the power source and the brake force based on the result of the calculation when the vehicle starts.
Abstract:
The present invention provides a brake system for a vehicle with an idle stop and go comprising a valve assembly disposed in a brake line for supplying brake pressure to the wheels by operation of the brake pedal to open or close the brake line; and a controller controlling the valve assembly.
Abstract:
A vehicle brake fluid pressure control apparatus includes: a control unit including a memory part for storing a valve closing map which shows a relationship between a differential pressure between an upstream side and a downstream side of a pressure regulator valve and an output current value for closing the pressure regulator valve and a valve opening map which shows a relationship between the differential pressure and an output current value for opening the pressure regulator valve, wherein the control unit executes a current value switching control in which the output current value of the valve closing map is changed to that of the valve opening map and thereafter, the output current of the valve opening map is changed to an output current value which lies somewhere between the output current values of the valve closing map and the valve opening map.
Abstract:
An exemplary embodiment of a Hill Start Aide system for a vehicle includes a brake system. The brake system including a brake actuator for manually actuating the brake system. The brake system is selectively configurable in a stopped configuration, where the brake system is manually maintained via the brake actuator such that a vehicle road wheel speed is about zero rpm, a released configuration, where the brake system will not generally inhibit rotation of at least one vehicle road wheel, and a control stop configuration, where the vehicle road wheel speed is about zero rpm. The Hill Start Aide system also includes a controller for at least partially controlling the brake system. The controller will selectively send a signal to maintain the brake system in the control stopped configuration when the brake actuator is manually released. The controller will send a signal to the brake system to release the brakes when a predetermined amount of time has elapsed after a transmission is manually shifted to a neutral configuration while the brake system is in the control stopped configuration.
