Abstract
A brake-by-wire system uses a time sequence type that determines road conditions before initialization, initializes EWBs (Electro Wedge Brake) at the left/right front wheels and EMBs (Electro Mechanical Brake) at the left/right rear wheels with time differences on the basis of the determined road conditions. Therefore, the clamping force in at least any one of the EWBs and the EMBs is maintained in any circumstances, thereby avoiding a situation that all the braking force of a vehicle is removed.
Claims14
A method of controlling a brake-by-wire system of a vehicle, the method comprising:
- providing a brake-by-wire system comprising a plurality of electrically controlled brakes, wherein the plurality of electrically controlled brakes comprises a first brake installed on a first wheel, a second brake installed on a second wheel, a third wheel installed on a third wheel and a fourth brake installed on a fourth wheel, wherein the first and second wheels are front wheels of a vehicle and the third and fourth wheels are rear wheels of the vehicle;
- determining whether the vehicle is on a slope;
- and
- when determined that the vehicle is on a slope, initializing two of the brakes among the first, second, third and fourth brakes while the other two brakes maintain braking of the corresponding wheels,
- wherein the vehicle comprises an engine located at a front location of the vehicle, wherein determining comprises determining whether the vehicle is on an uphill slope or a downhill slope,
- wherein, when determined that the vehicle is on the uphill slope, the first and second brakes installed in the front wheels are initialized before the third and fourth brakes are initialized,
- wherein, when determined that the vehicle is on the downhill slope, the first and third brakes are initialized before the second and fourth brakes are initialized, wherein the first and third brakes are diagonally arranged and the second and fourth brakes are diagonally arranged.
A method of controlling a brake-by-wire system of a vehicle, the method comprising:
- providing a brake-by-wire system comprising a plurality of electrically controlled brakes, wherein the plurality of electrically controlled brakes comprises a first brake installed on a first wheel, a second brake installed on a second wheel, a third wheel installed on a third wheel and a fourth brake installed on a fourth wheel, wherein the first and second wheels are front wheels of a vehicle and the third and fourth wheels are rear wheels of the vehicle;
- determining whether the vehicle is on a slope;
- and
- when determined that the vehicle is on a slope, initializing two of the brakes among the first, second, third and fourth brakes while the other two brakes maintain braking of the corresponding wheels,
- wherein the vehicle comprises an engine located at a rear location of the vehicle, wherein determining comprises determining whether the vehicle is on an uphill slope or a downhill slope,
- wherein, when determined that the vehicle is on the downhill slope, the first and second brakes are initialized after the third and fourth brakes are initialized,
- wherein, when determined that the vehicle is on the uphill slope, the first and third brakes are initialized after the second and fourth brakes are initialized, wherein the first and third brakes are diagonally arranged and the second and fourth brakes are diagonally arranged.
