Abstract: A behavior stabilizer of a vehicle braking force control device includes a plurality of first valves configured to control movement of a hydraulic fluid to respective friction brakes, second valves configured to control the movement of the hydraulic fluid to reservoirs, and a drive motor configured to drive pumps that pump the hydraulic fluid from the reservoirs into a path leading to a hydraulic pressure generator. When a vehicle is in a state of turning at a specific vehicle speed or lower, a controller executes a turning control to control operation of an electric actuator to cause the hydraulic pressure generator to generate hydraulic pressure, and to control open/closed states of the first valves and the second valves to apply a braking force to a plurality of wheels. The controller keeps the driving of the drive motor in a stopped state during the turning control.

Abstract: A vehicle control system, includes: a travel control unit configured to generate a first control signal for controlling a direction control device of a vehicle to make the vehicle travel along a road shape; a stability control unit configured to generate a second control signal for controlling the direction control device to stabilize behavior of the vehicle when the behavior of the vehicle is in a prescribed unstable state; and an arbitration unit configured to receive the first control signal and the second control signal and to output at least one of the first control signal and the second control signal to the direction control device. When the arbitration unit is receiving the second control signal, the arbitration unit reduces a control amount corresponding to the first control signal.

Abstract: A vehicle control device includes an information acquirer that acquires information on driving conditions of a vehicle at least containing a steering angle and a vehicle speed, a distribution amount setter that sets a distribution amount of a brake force to each of multiple wheels provided in the vehicle based on the driving conditions of the vehicle; and a brake controller that performs brake control of each of the multiple wheels according to the distribution amount set by the distribution amount setter. When the vehicle speed is equal to or lower than a 22nd vehicle speed value within a low vehicle speed range, the distribution amount setter sets the distribution amount of a brake force to each of the multiple wheels including a specific wheel to a value which is smaller than a distribution amount when the vehicle speed exceeds the 22nd vehicle speed value.

Abstract: The present invention includes: a camera that is mounted in a vehicle and that captures a forward-view image of the vehicle; a learner that learns a traveling line of the host vehicle in a lane from the image captured by the camera; and a vehicle controller that performs control of returning the vehicle to the learned traveling line when a yaw rate due to disturbance is generated. Moreover, in the lane, a range that has a predetermined width from a center of a traveling width is set as a learning range and a range other than the learning range is set as a no-learning range. The learner does not learn the traveling line in the no-learning range.

Abstract: A vehicle control device includes an information acquirer that acquires information on driving conditions of a vehicle at least containing a steering angle and a vehicle speed, a distribution amount setter that sets a distribution amount of a brake force to each of multiple wheels provided in the vehicle based on the driving conditions of the vehicle; and a brake controller that performs brake control of each of the multiple wheels according to the distribution amount set by the distribution amount setter. The distribution amount setter sets the distribution amount to zero when the steering angle SA is less than a first steering angle threshold where the steering angle SA is recognizable as a substantially neutral state.

Abstract: A vehicle control device includes a behavior detection part that detects a behavior of a vehicle in front traveling in front of an own vehicle in a same direction as the own vehicle, and a driving control part that performs at least a steering control of the own vehicle without depending on an operation of a driver of the own vehicle. The behavior detection part detects a peak of a lateral speed of the vehicle in front. When the own vehicle is traveling in a straight section, the driving control part executes, at an occurrence point of a lateral position change of the vehicle in front that caused the detected peak, a first steering control that outputs a steering force toward an opposite side of the lateral position change of the vehicle in front or amplifies a steering force output based on a predetermined reference.

Abstract: Disclosed are a vehicle control device and method. The vehicle control device includes: a turning state detection part for detecting whether the vehicle is in a turning state based on the driving state of the vehicle; a vehicle speed detection part for detecting whether the vehicle speed of the vehicle is equal to or less than a predetermined threshold; a braking force distribution control part for distributing and controlling the braking force of each wheel of the vehicle based on the driving state and the vehicle speed; and a brake noise detection part for detecting the brake noise of each of the wheels. When the braking force distribution control part controls the braking force and the brake noise occurs for multiple times within a predetermined time, the braking force distribution control of the braking force distribution control part is suppressed.
