Abstract
A communication method between a brake booster of a vehicle and an ESP control unit of the vehicle. In the method, a signal is coupled into a brake fluid, transported between the brake booster and the brake control unit over a brake line filled with the brake fluid, and extracted again from the brake fluid.
Claims15
A communication method between a brake booster of a vehicle and an ESP control unit of the vehicle, the communication method comprising the following steps:
- coupling a first signal into a brake fluid;
- transporting the first signal between the brake booster and the ESP control unit via a brake line filled with the brake fluid;
- extracting the first signal from the brake fluid, wherein:
- the first signal is a pressure modulation;
- and
- during the transporting of the first signal, at least one valve via which the brake fluid is transferrable to one or more brakes is closed;
- and
- opening the at least one valve in response to completion of the pressure modulation of the first signal.
A brake system, comprising:
- a brake booster of a vehicle;
- and
- an ESP control unit of the vehicle;
- wherein the brake system is configured to:
- couple a first signal into a brake fluid;
- transport the first signal between the brake booster and the ESP control unit via a brake line filled with the brake fluid;
- and
- extract the first signal from the brake fluid wherein the first signal is a pressure modulation;
- keep closed at least one valve via which the brake fluid is transferrable to one or more brakes for a duration of the transport of the first signal;
- and
- open the at least one valve in response to completion of the pressure modulation of the first signal.
A non-transitory machine-readable storage medium on which is stored a computer program for communicating between a brake booster of a vehicle and an ESP control unit of the vehicle, the computer program, when executed by a computer, causing the computer to perform a method, the method comprising:
- coupling a first signal into a brake fluid;
- transporting the first signal between the brake booster and the ESP control unit via a brake line filled with the brake fluid;
- extracting the first signal from the brake fluid, wherein:
- the first signal is a pressure modulation;
- and
- during the transporting of the first signal, at least one valve via which the brake fluid is transferrable to one or more brakes is closed;
- and
- opening the at least one valve in response to completion of the pressure modulation of the first signal.
