Embodiment Construction

[0019] figure 1 In a simplified plan view, a motor vehicle 1 is shown which, in addition to the drive unit 2 shown here, also has a braking system 3 . The drive device 2 includes in particular a drive machine M, such as an internal combustion engine and / or an electric machine, which is connected to the motor vehicle 1 , in particular via a clutch 4 and / or a transmission 5 with a plurality of switchable (well-bare) gear ratio stages. The driving wheel 6 is functionally connected. Furthermore, wheel brakes 7 of the braking system 3 are assigned to drive wheels 6 or other wheels of the motor vehicle 1 . The wheel brakes 7 have an integrated parking brake 8 which is in particular designed as an electric motor or electrohydraulic. If the parking brake 8 is actuated or voltage is applied to the parking brake 8 , a brake actuator 8 ′, for example an electric motor, is actuated, which in particular causes the brake piston of the wheel brake 7 The displacement creates a clamping for...

Abstract

The invention relates to a method for operating a starting aid of a motor vehicle having at least one parking brake (8), wherein the parking brake is released in response to an actuation of a accelerator pedal (11) of the motor vehicle (8), and wherein the disengagement of the parking brake (8) is released according to an amount representative of lane gradient (FS). It is provided that when the pedal (11) of the motor vehicle (1) reaches or exceeds a predeterminable release position by the actuation, the release takes place independently of the quantity or the availability of the quantity, so that Release the parking brake (8).

Description

technical field [0001] The invention relates to a method for operating a starting aid of a motor vehicle having at least one parking brake, wherein the parking brake is released as a function of an actuation of the accelerator pedal of the motor vehicle and wherein, as a function of a representative road gradient amount to release the disengagement of the parking brake. [0002] Furthermore, the invention relates to a device for operating a starting aid of a motor vehicle having at least one parking brake, wherein the parking brake has at least one electromechanical or electrohydraulic brake actuator capable of A parking brake actuating element actuated by the driver, a gradient detection device and a device for detecting the actuation of a gas pedal of the motor vehicle. [0003] Furthermore, the invention relates to a starting aid for a motor vehicle, which has a parking brake device with at least one actuatable brake actuator, which can be controlled by the machine. A par...
