Abstract: The braking control device generates braking force by operating an electric motor to press a friction member against a wheel-fixed rotary member. The braking control device includes: a wheel speed sensor detecting wheel speed; a rotation angle sensor detecting a motor rotation angle; a drive circuit driving the motor; and a controller controlling the drive circuit. The controller sets a current limit circle within d-axis/q-axis current characteristics of the motor based on specifications of the drive circuit, calculates a voltage limit circle within the d-axis/q-axis current characteristics based on the rotation angle, executes slip suppression control for reducing the degree of wheel slip based on the wheel speed, calculates d-axis and q-axis target current values based on intersection points of the current limit circle and the voltage limit circle when execution of slip suppression control begins, and controls the drive circuit based on the d-axis and q-axis target current values.

Abstract: The present disclosure provides an auto-braking system which includes a braking device, a receiver, and a controller. The controller includes a determining portion, a verifying portion and an executing portion. The determining portion determines whether a vehicle will violate a red signal of the traffic light based on the traffic light state information. The verifying portion verifies the traffic light state information is valid by comparing the traffic light state information with the image of the traffic light captured by the sensor. The executing portion executes a first braking control to slow the vehicle at a first deceleration rate when the determining portion determines that the vehicle will violate a red signal. The executing portion executes a second braking control to slow the vehicle at a second deceleration rate to stop at a specified position when the verifying portion verifies that the traffic light state information is valid.

Abstract: A method for operating a braking system of a motor vehicle equipped with a wheel-slip control device, wherein the braking system includes an electrohydraulic service brake, set to generate braking forces independently of an actuation by an operator. The system having a mechanical or electromechanical parking brake actuated by an actuating element, and acting, in particular, on the rear wheels of the motor vehicle. An operator-side intent to actuate the parking brake is recognized and subsequently during the actuation of the parking brake a hydraulic pressure of the service brake is generated that acts on at least one rear wheel, of the motor vehicle is capable of being braked by the parking brake. The hydraulic pressure sufficient to assist the parking brake and correspondingly lock the rear wheel of the motor vehicle braked by the parking brake during travel of the motor vehicle.

Abstract: A vehicle collision avoidance support apparatus includes a state determination unit configured to determine whether or not there is a state where a moving object proceeding in a direction intersecting with a traveling direction of a vehicle may exist; a first sensor configured to detect an object in front of the vehicle; and an avoidance operation control unit configured to cause the vehicle to perform a predetermined avoidance operation for avoiding a collision according to a detection result of the first sensor within a determination region in front of the vehicle. The avoidance operation control unit uses a region that is wider in a direction perpendicular and horizontal to the travelling direction as the determination region when it is determined that there is a state where the moving object may exist in comparison with when it is determined that there is no state where the moving object may exist.

Abstract: A method for operating a braking assistance system of a vehicle, wherein the braking assistance system assists a braking of the vehicle by a vehicle braking device in the event of a hazard braking. To differentiate between the hazard braking and a normal braking, at least two variables, representing a braking demand of a driver of the vehicle, are ascertained and a threshold value is established for each variable wherein hazard braking is recognized when at least the two variables exceed their particular threshold value, whereupon an automated braking intervention by the braking assistance system is initiated with the aid of the vehicle braking device. Furthermore, at least one driving-situation variable representing the instantaneous driving situation of the vehicle is ascertained and the at least two threshold values are changed depending on the at least one driving-situation variable.
