Abstract
A method for determining the triggering sensitivity of an automatic braking process in motor vehicles. By a control element the driver can control within a specific range the threshold value which is effective for triggering. The permissible range is selected so that the effective threshold value can neither be reduced to such an extent that automatic braking is triggered at actuation speeds of the brake pedal which are normal for travel mode, nor increased to such an extend that it is impossible to trigger automatic braking process.
Claims10
Apparatus for controlling activation sensitivity of a vehicle automatic braking system of the type wherein a brake pressure greater than that which corresponds to position of a brake pedal of said vehicle is applied to brakes of said vehicle whenever actuation speed of said brake pedal by a vehicle operator exceeds a predetermined threshold value, said apparatus comprising:
- a control device in a passenger compartment of said vehicle, said control device being operatively coupled to said vehicle automatic braking system, and having a moveable control element which is manually operable by said vehicle operator;
- means for varying said activation sensitivity of said vehicle automatic braking system according to performance and driving habits of said vehicle operator to achieve said vehicle operator's feeling of safety, by adjusting said predetermined threshold value of said actuation speed of said brake pedal as a function of position of said moveable control element;
- and
- means for limiting said adjusting of said predetermined threshold value to a predetermined range of values.
Method of controlling activation sensitivity of a vehicle automatic braking system of the type wherein a brake pressure greater than that which corresponds to position of a brake pedal of said vehicle is applied to brakes of said vehicle whenever actuation speed of said brake pedal by a vehicle operator exceeds a predetermined threshold value, said method comprising the steps of:
- providing a control device in a passenger compartment of said vehicle, said control device being operatively coupled to said vehicle automatic braking system, and having a moveable control element which is manually operable by the vehicle operator;
- and
- varying said activation sensitivity of said vehicle automatic braking system according to preference and driving habits of said vehicle operator in order to achieve said vehicle operator's feeling of safety, by adjusting said predetermined threshold value of said actuation speed of said brake pedal as a function of position of said manually operable moveable control element;
- wherein adjustment of said predetermined threshold value is limited to a predetermined range of values.
