摘要： A steering control device is configured to control a steering of a vehicle having at least one piloted actuator associated with a system for steering a wheel of the vehicle and a piloted actuator associated with a decoupled braking system at a wheel of the vehicle. The steering control device includes at least one control unit. The control unit is configured to recover at least one value characteristic of the travel of the vehicle and to issue a control instruction to the at least one piloted actuator according to the recovered value(s). The control unit includes a calculation module in which a model of a lateral dynamic behavior of the vehicle frame is implemented. At least one specific physical quantity of the lateral dynamic behavior is expressed according to the specific drifts of each set of front wheels and rear wheels of the vehicle.

摘要： A method for braking a vehicle, including checking whether a trigger criterion for braking the vehicle is present, and if the trigger criterion is satisfied, causing a conditioning braking pulse through brief pulsed braking such that passengers experience brief braking of the vehicle, and immediately thereafter initiating a braking phase in which the vehicle is braked in at least two partial braking regions by an actual ego deceleration that varies with respect to time, wherein each partial braking region is extended over a partial braking interval and merge into one another without the actual ego deceleration changing abruptly, and the actual ego deceleration in at least one of the partial braking regions is changed continuously over the respective partial braking interval such that a different actual jerk is obtained in each partial braking region, and wherein the actual jerk behaves degressively over at least some partial braking regions.

摘要： A braking control device, when stopping a vehicle in a state where a braking force is being applied to the vehicle, executes a reducing control of reducing the braking force corresponding to a braking request before the vehicle stops and executes an increasing control of increasing the braking force corresponding to the braking request before the reducing control in order to suppress vehicle pitching behavior generated when the braking force is applied to the vehicle. The control device sets braking force increase amount in the increasing control based on a difference distance that is a difference between a first distance correlated with a vehicle traveling distance from a reduction start timing when the reducing control is executed until the stopping of the vehicle and a second distance correlated with a vehicle traveling distance from the reduction start timing when the reducing control is not executed until the stopping of the vehicle.

摘要： A method can be used to control a steer-by-wire steering system in an emergency steering mode. The method comprises checking a steering system for the presence of a fault state and upon detection of a fault implementing the emergency steering mode, which involves determining a setpoint position of a steering tie rod using a setpoint wheel steering angle, determining a front wheel to be braked and a brake pressure to attain the setpoint position with a control unit, transmitting the front wheel to be braked and the brake pressure to a brake system, braking the front wheel to be braked, and increasing a torque provided by a wheel drive to compensate for a loss of speed of the motor vehicle caused by the braking of the front wheel to be braked.

摘要： In the case that the road surface is determined to have different friction coefficients on the left and right wheels, this braking control device performs antiskid control for adjusting the increase slope of front wheel braking torque on the side with the higher friction coefficient. A steering angle sensor detects the steering angle, and a yaw rate sensor detects the yaw rate. The device calculates a reference turning amount on the basis of the steering angle, calculates an actual turning amount on the basis of the yaw rate, and sets the increase slope on the basis of the deviation between the reference turning amount and the actual turning amount. Also, if this deviation becomes larger, a correction is made such that the set increase slope becomes smaller. Further, if the deviation becomes smaller, a correction is made such that the set increase slope becomes larger.

摘要： A trailer oscillation and stability control device including an accelerometer and an angular rate sensor. An oscillation detection discriminator detects oscillatory lateral trailer motion in response to trailer displacement data derived from inputs from the angular rate sensor and acceleration signals received from the accelerometer, and then generates corresponding oscillatory event data. A brake controller generates a braking control signal in response to oscillatory event data received from the oscillation detection discriminator.
