Embodiment Construction

[0019] figure 1 Motor vehicle 1 is shown in a simplified plan view. The motor vehicle 1 has a front axle 2 and a rear axle 3 which each have two wheels 4 or 5 which are in contact with the roadway for the acceleration torque or deceleration A torque is applied to motor vehicle 1 .

[0020] To accelerate the vehicle 1 , the vehicle has a drive system 6 with here two drive mechanisms 7 and 8 . The first drive 7 is designed as an internal combustion engine and is operatively connected or connectable to the wheels 4 of the axle 2 via a transmission 9 and a clutch (not shown). The second drive 8 is designed as an electric motor, which is operatively connected via a transmission 10 to the wheels 5 of the rear axle 3 . Different positive or negative torques can thus be generated on the axles 2 and 3 via the drives 7 and 8 . Motor vehicle 1 can also have only one of drive units 7 , 8 .

[0021]In order to decelerate the motor vehicle 1 , the motor vehicle has a vehicle braking sy...

Abstract

The invention relates to a method for operating a motor vehicle having a primary brake system (14) and a secondary brake system (11), wherein a wheel brake (15, 16) which can be actuated by the brakesystems (14, 11) is associated with each wheel (4, 5) of the motor vehicle, wherein in an emergency braking mode the secondary brake system (11) is activated in such a way that the wheel brakes (15, 16) in each case produce the same braking force. According to the invention, in the emergency braking mode a current steering angle of the motor vehicle is detected and the secondary brake system is activated as a function of the detected steering angle.

Description

technical field [0001] The invention relates to a method for operating a motor vehicle with a primary braking system and a secondary braking system, wherein each wheel of the motor vehicle is assigned a Hydraulically actuated wheel brakes, wherein in emergency braking mode the secondary brake system is actuated such that the wheel brakes each generate the same braking force. [0002] Furthermore, the invention relates to a device for operating a motor vehicle with a primary brake system and a secondary brake system as well as at least one drive, wherein each wheel of the motor vehicle is assigned a Wheel brakes that can be hydraulically actuated via the brake system; the device has a controller designed to actuate the brake system in emergency braking mode in the event of failure of the primary brake system The secondary braking system enables the wheel brakes to produce the same braking force. [0003] Furthermore, the invention relates to a motor vehicle with a correspondi...
