Abstract
A control system (11) for a vehicle (10) includes vehicle dynamics sensors (35-47) providing a vehicle dynamics signal. Tire monitoring system sensors (20) in each wheel generate tire signals including temperature, pressure and acceleration data. A controller (26) communicates with the tire monitoring system sensors (20) and at least one vehicle dynamics sensor, and generates a roadway surface condition estimation value as a function of the multi-axis acceleration data of the tire signals. The roadway surface condition estimation value is transmitted to a suspension control system (33) to adjust the vehicle suspension characteristics in response to the roadway surface condition estimation value.
Claims13
A system for a vehicle comprising:
- a tire sensor located within a wheel of the vehicle and generating a tire signal comprising pressure, temperature and multi-axis acceleration data;
- at least one vehicle dynamics sensor providing a vehicle dynamics signal;
- and
- a controller communicating with the tire sensor and the at least one vehicle dynamics sensor, the controller, in response to the vehicle dynamics signal, generating a roadway surface condition estimation value as a function of the multi-axis acceleration data of the tire signal, and transmitting the roadway surface condition estimation value to at least one vehicle system controller.
