Abstract
The invention relates to a method for determining the start of an automatic braking process. In those instances where the brake pedal is actuated starting from an initially unactuated position, triggering of automatic braking occurs when the actuation speed of the brake pedal remains above a threshold trigger value for automatic braking, and a prescribed pedal travel is exceeded in a specific time interval after the start of the actuation of the brake pedal. Light depression of the brake pedal which takes place only briefly at a high pedal actuation speed does not lead to the automatic braking process being triggered.
Claims10
In an automatic braking system of the type wherein during automatic braking, braking pressure is applied which is greater than that which corresponds to a position of a brake pedal of said system, a method for determining the start of automatic braking comprising the steps of:
- detecting the position of said brake pedal relative to an unactuated rest position thereof;
- detecting an actuation of said brake pedal;
- detecting an actuation speed and a pedal travel of said brake pedal;
- and
- when said actuation of said brake pedal commences from an at least substantially unactuated position of said brake pedal, triggering said automatic braking when both of the following are satisfied;
- actuation speed of said brake pedal in a direction which increases braking pressure satisfies a triggering criterion;
- and
- pedal travel of said brake pedal during a prescribed time interval after the start of said actuation of the brake pedal exceeds a prescribed threshold value.
