Abstract
In a method for the automatic parameterization of a braking system in a vehicle, a brake pressure profile is predefined as a test run during a test drive operation, and the wheel slip which thereafter arises is ascertained. If the wheel slip is outside a permissible value range, the brake pressure is modified and a new test run is carried out.
Claims14
A method for automatic parameterization of a braking system in a vehicle that has at least one wheel, the method comprising the following steps:
- obtaining a predefined brake pressure profile;
- during a test drive of the vehicle:
- controlling the brake system to perform a braking according to the brake pressure profile that has been predefined;
- and
- using at least one sensor of the vehicle to ascertain a wheel slip which arises from the brake pressure profile at the at least one wheel of the vehicle;
- determining that a value of the ascertained wheel slip value or of a gradient of the ascertained wheel slip is outside a permissible value range;
- determining a point in time in the brake pressure profile at which a brake pressure or a gradient of the brake pressure is a cause of the value of the ascertained wheel slip or of the gradient of the ascertained wheel slip being outside the permissible value range;
- and
- based on the determined point in time:
- modifying the obtained predefined brake pressure profile to thereby obtain a modified brake pressure profile;
- and
- storing brake control parameters corresponding to the modified brake pressure profile in the braking system, the braking system being configured to perform a wheel slip control according to the stored brake control parameters.
