A braking control system includes control circuitry configured to control first and second brakes in a vehicle. The control circuitry is configured to calculate a target braking force in accordance with the operation amount of a brake pedal by a driver, determine a first braking force and a second braking force based on the target braking force, and control each of the first and second brakes such that each of the determined braking forces is generated in the vehicle. The first and second braking forces are determined such that a sum of the first and second braking forces becomes the target braking force and a pitch behavior specified by a preset pitch behavior model occurs in the vehicle.

A vehicle control device includes an automatic driving control device configured to execute automatic driving control on a vehicle, and an anti-lock braking system configured to control a longitudinal slip ratio of wheels of the vehicle to be equal to or smaller than a threshold during braking of the vehicle.

A collision avoidance assist apparatus includes: a front-and-lateral target information acquisition device configured to acquire front-and-lateral target information; a vehicle information acquisition device configured to acquire vehicle information including a vehicle speed and at least one of a yaw rate or a steering input value; and a control unit configured to execute collision avoidance assist control when a target satisfies a collision condition that is satisfied when the target is determined to have collision possibility. The control unit selects targets that satisfy a predetermined selection condition from targets in the front-and-lateral target information, determines whether the collision condition is satisfied for each selected target, determines, when this determination is to be made, whether an own vehicle is turning based on the vehicle information, and changes the selection condition between a case in which the own vehicle is not turning and a case in which the own vehicle is turning.

The present invention provides a vehicle control device that can reduce the delay in the deceleration response of a vehicle to a deceleration command. The present invention modifies the distribution ratio of brake fluid pressure between front brakes and rear brakes on the basis of lateral motion information, vehicle information, and a collision risk or a traveling scene obtained from information pertaining to the external surroundings. The brake fluid pressure is distributed to only one of the front brakes or the rear brakes.

A vehicle includes an axle, electric machine, friction, brakes, and a controller. The axle has an input shaft to an open differential and output shaft extending out of the open differential. The electric machine is secured to the input shaft and wheels are secured to the output shafts. The controller is programmed to, in response to an anti-locking braking event, generate a signal indicative of a total torque demand to brake the vehicle based on a difference between a desired and an actual wheel slip ratio, adjust a regenerative braking torque of the electric machine based on signal and a regenerative braking weighting coefficient to maintain or drive actual wheel slip toward the desired wheel slip, and adjust a friction braking torque of the friction brakes based on the signal and a friction braking weighting coefficient to drive actual wheel slip at or toward the desired wheel slip.

A system and method for controlling the velocity of a vehicle includes a processor, a velocity sensor in communication with the processor, a throttle actuator in communication with the processor, and a brake actuator in communication with the processor. The processor is set either the throttle position of the vehicle via the throttle actuator or the brake pedal position of the vehicle via the brake actuator based whether the augmented acceleration is greater than or equal to a gear acceleration, whether the actual velocity is above a crawl speed, and a lookup table.

Systems and methods for controlling a vehicle. The system includes a plurality of sensors and an electronic controller. The electronic controller is configured to receive data from the plurality of sensors and determine a target vehicle travel direction of the vehicle based on the received data. The electronic controller then determines a heading error based on the target travel direction, determines a heading error derivative, and generates a vehicle control command based on the heading error and the heading error derivative.
