Problems solved by technology

Today's brake devices have the disadvantage that a loss of clamping force can occur if the brake device cools down after the stopping moment
However, today's brake disc-temperature models are relatively imprecise, since they are additionally influenced by many environmental variables such as temperature, weather conditions, wheel material and shape, wheel guards, wheel size, add-ons and similar factors

Embodiment Construction

[0022] figure 1 A wheel brake device 1 of a motor vehicle, which is not shown in detail here, is shown in a simplified sectional illustration. The wheel brake device 1 is designed as a disc brake and for this purpose has a brake caliper 2 with brake linings 3 between which the brake pads 3 can be clamped or clamped with The wheels of the motor vehicle have brake discs 4 connected in a rotationally fixed manner. For this purpose, a hydraulic actuator 5 is assigned to the brake caliper 2 , which has a brake piston 6 which can be hydraulically actuated in order to move the The brake disc 4 is clamped between the brake linings 3 . During driving operation, a braking torque is thus applied to brake disk 4 and thus to the wheels, which serves to decelerate the vehicle.

[0023] In addition, the wheel brake device 1 is designed as a parking brake device and has an electric actuator 7 for this purpose, which is composed of an electric motor 8 , an actuator drive 9 designed here as ...

Abstract

The invention relates to a method for operating a brake system (1), in particular a parking brake system, of a vehicle, wherein the brake system (1) has an electric actuator (7), which The actuator element (10) can be moved selectively into a clamping position for applying a clamping force to the brake disc (4) or into a release position for releasing said brake disc (4), wherein the brake disc temperature is ascertained , in order to actuate the actuator (7) as a function of the determined brake disc temperature, characterized in that the brake disc temperature is determined as a function of at least one current value of the actuator (7).

Description

technical field [0001] The invention relates to a method for operating a brake device of a vehicle, in particular a parking brake device, wherein the brake device has an electric actuator which can selectively move an actuator element to In a clamping position (Zuspannstellung) in which a clamping force is applied to the brake disc or in a release position in which the brake disc is released, wherein the brake disc temperature is ascertained in order to control the brake disc as a function of the ascertained brake disc temperature Actuator. [0002] Furthermore, the invention relates to a device for carrying out the method as well as to a braking device having such a device. Background technique [0003] Methods, devices and braking devices of the type mentioned at the outset are known from the prior art. In particular, automatic parking brake systems of the "motor-on-caliper" type are usually used on the rear wheel brakes of motor vehicles in order to apply the wheels of ...
