Method and device for brake control in a vehicle during the starting process
A method for brake regulation in a vehicle when driving off on a split-μ roadway is provided, in which method the presence of a drive-off procedure on a split-μ roadway having a high coefficient of friction side and a low coefficient of friction side is recognized, and as a result, the brake pressure on a driven wheel on the high coefficient of friction side of the vehicle is increased.
1. A method of regulating brakes in a vehicle when driving off on a roadway having a first portion with a higher coefficient of friction than a second portion, comprising:
identifying that the vehicle is driving off on the roadway having a first portion with a higher coefficient of friction than a second portion; and
increasing the brake pressure on a driven wheel on the portion of the roadway having the higher coefficient of friction;
wherein the brake pressure on the driven wheel on the portion of the roadway having the higher coefficient of friction is increased by a first constant value if a parking brake of the vehicle is not actuated by the driver, and wherein the brake pressure on the driven wheel on the portion of the roadway having the higher coefficient of friction is increased by a second constant value higher than the first constant value if the parking brake is actuated by the driver.
2. A device for brake regulation in a vehicle when driving off on a roadway having a first portion with a higher coefficient of friction than a second portion, comprising:
a recognition unit for recognizing that the vehicle is driving off on the roadway having a first portion with a higher coefficient of friction than a second portion; and
a brake pressure increasing unit for increasing the brake pressure on a driven wheel on the portion of the roadway having the higher coefficient of friction once the recognition unit recognizes that the vehicle is driving off on the roadway having a first portion with higher coefficient of friction than a second portion;
wherein the brake pressure is increased by a first constant value if a parking brake is not actuated by the driver, and wherein the brake pressure is additionally increased by a second constant value if the parking brake is actuated by the driver.
