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.

In a method for activating and deactivating a control unit which can be used to control an electrically activatable assembly, the control unit is switched between a waking state, a sleep state and a deactivated state, wherein in the sleep state, the control device is disabled but can be transferred into the waking state by means of a sensor signal.

The trailer includes a left wheel, a right wheel, an axle, a left brake device coupled to the left wheel, and a right brake device coupled to the right wheel.

Disclosed may be a method for controlling counter steering of a vehicle, which, in a counter steering section for controlling over-steer while a vehicle travels a curve, prevents lateral force from being decreased by maintaining a braking pressure according to an operation of an antilock braking system (ABS) for a vehicle wheel (a front axle curve-travelling outer wheel) of a counter steering target at an optimal slip level (before an improvement of a target slip), and improves steering performance by forming a linear yaw rate in a direction for counter steering without a delay in forming the yaw rate.

A control system for a vehicle is provided, which includes a driving force source configured to generate torque for driving drive wheels, a steering wheel, a steering angle sensor, and a controller. Based on the detected steering angle, the controller reduces the driving torque to add deceleration to the vehicle when the steering wheel is being turned in one direction, and increases the torque to add acceleration when the steering wheel is being turned back in the other direction. The controller controls the torque, when the steering wheel is being turned in the returning direction from a state where it is turned in the one direction, so as to add forward acceleration until the steering wheel returns to a neutral position, and when the steering wheel is then being turned in the other direction after passing through the neutral position, so as not to add the forward acceleration.

The vehicle drive system comprises: a torque generating device; a differential mechanism that allows a relative rotation between a right wheel and a left wheel; a differential restricting device that restricts a differential rotation between the right wheel and the left wheel; and a steering mechanism that controls a turning angle of pairs of the wheels. A first controller controls the relative rotation between the right wheel and the left wheel to be smaller than a predetermined value and second controller further controls a turning angle of the wheels controlled by the steering mechanism.

The vehicle behavior control device further comprises: a steering angle sensor (8); a vehicle speed sensor (10); a yaw rate sensor (12); and a yaw moment setting part (22) in PCM (14) configured to decide a target yaw rate of the vehicle based on a steering angle and a vehicle speed, and set, based on a change rate of a difference between an actual yaw rate and the target yaw rate, a yaw moment oriented in a direction opposite to that of the actual yaw rate of the vehicle, as a target yaw moment, whereby the brake control system can regulate the braking forces of the road wheels so as to apply the target yaw moment to the vehicle.

A vehicle control apparatus has a steering wheel 6, an engine 4 for outputting a driving force of a vehicle 1, a brake apparatus 16 capable of applying different braking forces to left and right wheels, and a PCM 14 including a processor and the like. When executing vehicle yaw control, which controls the brake apparatus 16 to apply to the vehicle 1 a yaw moment in the direction opposite to the yaw rate generated in the vehicle 1, after executing vehicle attitude control for reducing an output torque of the engine 4 based on a turning operation of the steering wheel 6, when the control amount of the vehicle attitude control is large, the PCM 14 increases the control amount of the vehicle yaw control compared to when the control amount of the vehicle attitude control is not large.

A stably braking system and a method using the same control wheels on a single axle of a ground vehicle. Firstly, at least one of a wheel deceleration and an actual slip of each of the wheels is calculated.

Hydraulic control commands are generated when a braking operation is performed in response to a braking indication signal and it is detected that the wheel deceleration or the actual slip is higher. The hydraulic control commands are configured to control a hydraulic braking system to adjust the wheel speed. When the ground vehicle drives in a straight line or turns with a first pose physical quantity, the hydraulic control command with a low priority is replaced by the hydraulic control command with a high priority and the hydraulic braking system is controlled to adjust the wheel speeds based on the identical hydraulic control commands.
