Abstract
This disclosure relates to equipment of a partly autonomously or autonomously operated motor vehicle. The equipment includes an electrically actuating service brake device which carries out at least one service brake function, an electrically actuating parking brake device which has at least one applied state and a released state, a drive device which has at least one active state for driving the motor vehicle and an inactive state, a starter device which produces a starting signal which transfers the drive device from the inactive state into the active state, and an electrical energy source. This disclosure also relates to an electronic control device which is in signal connection with the parking brake device and the starter device.
Claims15
A system for a partially autonomously or autonomously operated motor vehicle, comprising:
- a) an electrically actuatable service brake device that performs at least one service brake function,
- b) an electrically actuatable parking brake device that performs at least one parking brake function and has at least one applied state and a released state,
- c) a drive device that has at least one active state for driving the motor vehicle and an inactive state in which the drive device is shut down,
- d) a starter device which generates a starting signal which transfers the drive device from the inactive state into the active state, and
- e) an electrical energy source which supplies electrical energy to at least the electrically actuatable service brake device and the starter device, characterized in that
- f) an electronic control device is provided which has a signal connection to at least the parking brake device and the starter device and which receives from a sensor device an actual value for an electrical supply voltage or a physical variable, representing said actual value, of the electrical energy source, wherein
- g) the electronic control device is designed to be able to determine with the aid of the signal connection whether the parking brake device is in the applied state and the starter device has generated the starting signal, and if this is the case, the electronic control device keeps the parking brake device in the applied state for as long as the actual value for the electrical supply voltage, or the physical variable representing said actual value, has not reached or overshot a supply voltage minimum value.
