A collision avoidance support device for a vehicle that includes an obstacle detection device for detecting an obstacle in front of the vehicle and an electronic control unit configured to perform automatic brake control that automatically applies braking force to a vehicle when it is determined that the obstacle detection device have detected an obstacle and the vehicle may collide with the obstacle, and the electronic control unit is configured to prohibit the automatic brake control when the vehicle is towing a trailer and a friction coefficient of a road surface is determined to be lower than a standard value.

The vehicle control device: controls the drive device and the braking device such that an actual acceleration representing an actual acceleration of the vehicle coincides with a target acceleration for driving the vehicle so that the vehicle stops at a preset target stop position; acquires the target acceleration every time a predetermined time elapses, and sets the target acceleration to a value such that the magnitude of the change amount does not exceed the threshold change amount when the magnitude of the change amount representing the difference between the target acceleration and the previous target acceleration exceeds the threshold change amount; and sets the threshold change amount to a larger value than when the emergency condition is not satisfied in a case where a predetermined emergency condition is satisfied in a case where a driving force or a braking force larger than in a normal state is required.

A driver assistance system includes a braking module and a module for controlling emergency braking distance. The braking module is intended to be connected to brakes. The module for controlling braking distance is connected to an output of the braking module.

A vehicle includes at least one brake assembly configured to brake at least one wheel of the vehicle in response to an applied voltage. A power supply is in signal communication with the at least one brake assembly. The power supply is configured to operate in a first mode that outputs a first voltage and a second mode that outputs a second voltage greater than the first voltage. A brake control system is in signal communication with the at least one brake assembly and the power supply. The brake control system is configured to determine a driving state of the vehicle, and is configured to output a brake boost request signal to initiate the second mode of the power supply in response to detecting the driving state, wherein a braking response time of the at least one brake assembly is improved in response to applying the second voltage.

A collision avoidance device includes, for example, a collision avoidance executor, a determiner, and a collision avoidance controller. The collision avoidance executor can execute a collision avoidance function for a vehicle to avoid collision with an object to be avoided. The determiner determines, when a driver operates a steering, whether to be able to avoid the collision with the object to be avoided, based on a turning parameter related to a turning caused by the steering. The determiner determines whether to be able to avoid the collision with the object to be avoided by determining whether a lateral acceleration or a yaw rate serving as the turning parameter is equal to or greater than a first threshold. The collision avoidance controller inhibits the execution of the collision avoidance function when the lateral acceleration or the yaw rate of a vehicle is equal to or greater than the first threshold.

A method in which the driving behavior of a vehicle is influenced depending on surroundings data in order to support an evasive maneuver as soon as a risk of collision is detected using the data from surroundings sensors and vehicle sensors. The vehicle has an electronically regulated braking system which allows a driver-independent build-up and a modulation of the braking forces on the individual wheels of the vehicle, and a steering input by the drive is supported in the event of a detected risk of collision by a driver-independent braking intervention. A brake slip of at least one wheel of the vehicle is limited to a first slip threshold in a first phase of the evasive maneuver and to a second slip threshold in a second phase of the evasive maneuver, wherein the first slip threshold is smaller than the second slip threshold. The invention further relates to an electronic controller.

A vehicular collision avoidance system includes a sensor disposed at a vehicle for sensing exterior and forwardly of the vehicle. A processor processes sensor data captured by the sensor to determine the presence of a pedestrian ahead of the vehicle and outside a path of travel of the vehicle. The processor determines a projected path of travel of the pedestrian based on movement of the pedestrian. The processor determines where the forward path of travel of the vehicle intersects the projected path of travel of the pedestrian. The system, responsive at least in part to prediction that the pedestrian will be in the forward path of travel of the vehicle when the vehicle time to intersection elapses, adjusts the speed of the vehicle based at least in part on attentiveness of a driver of the vehicle and a driving condition of the vehicle.

A vehicle control device includes a vehicle position calculating unit, an obstacle determining unit, a collision possibility determining unit, an avoidance means selecting unit, an avoidance route calculating unit, and a steering control value calculating unit that calculates a steering control value and that outputs the steering control value to a steering actuator control unit. The avoidance route calculating unit calculates a target point for avoiding the obstacle, divides an avoidance section connecting the position of the vehicle to the target point into a plurality of partial sections, calculates a partial avoidance route in each of the partial sections, and calculates the avoidance route made up of the plurality of partial avoidance routes.

An autonomous vehicle which includes multiple independent control systems that provide redundancy as to specific and critical safety situations which may be encountered when the autonomous vehicle is in operation.

A drive source controller is configured to control a drive torque of a drive source that drives a vehicle. The drive source controller is configured to prohibit acceptance of drive source required torque from a cruise controller when automatic braking control is activated during cruise control, or not output the drive source required torque to the drive source controller when the automatic braking control is activated during the cruise control.
