The disclosure relates to a method for actuating an electrical drive of a trailer vehicle with a towing vehicle. According to an embodiment, the method include the steps of: determining a current mass of the towing vehicle; determining a current drive force of the towing vehicle; determining an acceleration demand in dependence upon the current mass and the current drive force; and, actuating the electric drive via an actuating signal in dependence upon the acceleration demand. The disclosure also relates to a control device for executing the method, a towing vehicle, a trailer vehicle and a semi-trailer truck.

Method and device for actuating an electrical drive of a trailer vehicle

A velocity adjustment system for adjusting a driving velocity of a includes a driver control device configured to receive actuation input from a driver, the actuation input including an actuation parameter. The system further includes an actuation sensor configured to detect the actuation parameter and to output a sensor signal and a velocity control device configured to record the sensor signal and evaluate the actuation input. The velocity control device is designed to compare the actuation parameter with a reference value and to output, based on the comparison, a request signal to an engine control device or a braking request signal to brake control device of a brake system.

A method for adjusting brake pressures on wheel brakes of a motor vehicle includes adjusting, in a normal braking mode as a function of a driver's braking demand determined by a driver of the motor vehicle, the brake pressures on the wheel brakes. The method further includes carrying out, by a brake control unit in a pressure control mode, adjustment of the brake pressures on the wheel brakes to implement at least a drive stability function and/or external braking demands. Furthermore, the method includes determining, by the brake control unit, the brake pressures on the wheel brakes at least when implementing external braking demands while controlling an ideal pressure distribution ratio of the brake pressures at wheel brakes of the front axle to the brake pressures at wheel brakes of a rear axle of the motor vehicle, wherein the control function takes into account a pressure distribution ratio.

Method for adjusting brake pressures, brake system of a motor vehicle for carrying out such method, and motor vehicle comprising such a brake system

A method for operating an electronic brake system for motor vehicles includes determining, by a brake control unit, respective brake pressures acting on wheel brakes by controlling a pressure distribution ratio of brake pressures acting on wheel brakes of a front axle to brake pressures acting on wheel brakes of a rear axle of the motor vehicle. The method further includes receiving, by the brake control unit, driver brake requests determined by a driver of the motor vehicle and/or external brake requests and determining, by the brake control unit, appropriate brake pressures. The brake control unit takes into consideration an initial pressure distribution ratio value, which is ascertained in a driver braking mode or in a pressure control mode and is stored and kept available for later consideration.

A method for electronically setting the brake force distribution of a desired total braking force in partial braking forces to the axle of a motor vehicle in dependence on the differential slip is provided. The differential slip is detected as the difference of the slip values of a variable representing the slip at the respective axle and is assigned to a relevant pair of axles. One of the axles is selected as a reference axle and the respective differential slip of a pair of axles is determined as the difference of the slip value at the reference axle and of the respective slip value of one of the further axles.

A method includes ascertaining a first drive force and a second drive force for a first drive axle and a second drive axle of a vehicle, ascertaining a first slip value and a second slip value for the first drive axle and the second drive axle of the vehicle, determining a first slip measured value for the first drive axle from the first drive force and the first slip value and determining a second slip measured value for the second drive axle from the second drive force and the second slip value, determining a total torque that is to act altogether on the first drive axle and the second drive axle, and dividing the total torque into a first desired torque and a second desired torque in dependence upon the first slip measured value and the second slip measured value.

Method for actuating electric motors in serial hybrid vehicles or fully electric vehicles having at least two separately driven axles

A method for determining the mass m of a motor vehicle, in particular a commercial vehicle, is based on the principles of power mechanics. In order to determine the vehicle mass in a simple way as accurately as possible while driving, a speed v of the motor vehicle is determined and a drive power Pof the motor vehicle is determined. The mass m of the motor vehicle can then be determined from the speed v and the drive power P. A device applies such a method, and a motor vehicle includes such a device.
