Abstract
An electric vacuum pump backup control system includes a brake on/off switch, a primary electric vacuum pump control interfacing with the brake on/off switch, a secondary electric vacuum pump control interfacing with the brake on/off switch and the primary electric vacuum pump control and an electric vacuum pump interfacing with the primary electric vacuum pump control.
Claims20
An electric vacuum pump backup control system, comprising:
- a brake on/off switch;
- a primary electric vacuum pump control interfacing with the brake on/off switch;
- a secondary electric vacuum pump control interfacing with the brake on/off switch and the primary electric vacuum pump control;

2 more elements
An electric vacuum pump backup control system, comprising:
- a brake on/off switch;
- a primary electric vacuum pump control interfacing with the brake on/off switch;
- a secondary electric vacuum pump control interfacing with the brake on/off switch and the primary electric vacuum pump control;
- an electric vacuum pump interfacing with the primary electric vacuum pump control;
- wherein the secondary electric vacuum pump control is adapted to operate the electric vacuum pump responsive to loss of communication with the primary electric vacuum pump control and responsive to receiving a request for activation from the primary electric vacuum pump control;
- and
- wherein the primary electric vacuum pump control is adapted to resume operation of the electric vacuum pump responsive to restoration of communication between the primary electric vacuum pump control and the secondary electric vacuum pump control and responsive to receiving a request for deactivation from the secondary electric vacuum pump control.
4 more elements
An electric vacuum pump backup control method, comprising:
- operating an electric vacuum pump using a primary electric vacuum pump control;
