Abstract
A vehicle braking system is responsive to vehicle conditions to alter the response of the braking system for a given driver input. In one mode, the vehicle conditions are conditions that are indicated by sensor in real time. In another mode, the vehicle conditions are historical conditions, such as trends, patterns, etc. The braking system provides braking responses that are appropriate for vehicle conditions and enables personalization of the braking system to accommodate individual driver characteristics.
Claims15
A braking system for a vehicle comprising:
- a driver-operable control input device having a selectively movable member;
- and
- a braking system actuator having an actuator characteristic with a selectively variable actuator characteristic value;
- wherein the braking system is sufficiently configured such that the variable actuator characteristic value is dependent upon the position of the member according to a first relationship when a first predetermined condition exists;
- and wherein the braking system is sufficiently configured such that the variable actuator characteristic value is dependent upon the position of the member according to a second relationship different from the first relationship when a second predetermined condition exists.
A method of controlling a brake system in a vehicle characterized by a vehicle condition having a variable vehicle condition value, the method comprising:
- monitoring the variable vehicle condition value;
- monitoring the position of a movable member of a driver-operable input device;
- determining whether the variable vehicle condition value indicates that a predetermined condition exists;
- and
- causing an actuator characteristic of a braking system actuator to be dependent upon the position of the movable member in accordance with a first relationship in response to the variable vehicle condition value not indicating that the predetermined condition exists;
- and
- causing the actuator characteristic of the braking system actuator to be dependent upon the position of the movable member in accordance with a second relationship in response to the variable vehicle condition value indicating that the predetermined condition exists.
A braking system for a vehicle comprising:
- a driver-operable control input device having a selectively movable member;
- and
- a braking system actuator having an actuator characteristic with a selectively variable actuator characteristic value;
- wherein the braking system is sufficiently configured such that the variable actuator characteristic value is a first function of the position of the member when a first predetermined condition exists;
- and wherein the braking system is sufficiently configured such that the variable actuator characteristic value is a second function of the position of the member when a second predetermined condition exists.
