摘要： A method for carrying out autonomous braking in a two-wheeled motor vehicle, where the necessity of vehicle deceleration is detected with the aid of a surround sensor system. When vehicle deceleration is necessary, prior to its execution, a test braking action independent of a rider and of a predefined temporal length is carried out. During or after the execution of the test braking action, a rider readiness variable characterizing the readiness of the rider to master the vehicle deceleration detected as necessary is ascertained. After completion of the test braking action, the vehicle deceleration is initiated, the time characteristic of the vehicle deceleration being a function of the rider readiness variable.

摘要： The present invention obtains a controller and a control method capable of simultaneously achieving freedom of driving and safety of a lean vehicle.
In a controller (60) and the control method according to the present invention, a control section of the controller (60) can execute anti-lock braking operation for suppressing locking of a rear wheel (4) by increasing/reducing a braking force or drive power of the rear wheel (4) of a lean vehicle (100) and thereby controlling a slip degree of the rear wheel (4) to a slip degree target, and in the case where a slide request, which is a request by a rider to make the lean vehicle (100) slide, is present, implements a slide control mode in which the anti-lock braking operation is performed by setting the slip degree target to be higher than that of a case where the slide request is absent.

摘要： A method controls a brake system of a vehicle combination. The switching valve in the second setting (anti-jackknifing braking function active) outputs a reservoir pressure into a trailer pressure line to actuate the trailer service brakes dependent on the anti-jackknifing braking demand. When service braking demand and anti-jackknifing braking demand are simultaneously present, an anti-jackknifing and a service braking ratio value are determined, a switchover criterion is checked dependent on the ratio values. The criterion is satisfied if the service braking ratio value exceeds a specified fraction of the anti-jackknifing braking ratio value when the anti-jackknifing braking function is active and falls below the specified fraction when the anti-jackknifing braking function is inactive; and, if the criterion is satisfied, the switching valve is switched over to activate the anti-jackknifing braking function and implement the anti-jackknifing braking demand, or to deactivate the anti-jackknifing braking function and implement the service braking demand.
