Abstract
A control system (10) for a vehicle (16) includes a sensor (35-47) that generates a sensor signal and a stability control system (26). Tire monitoring sensors (20) in each wheel generate tire signals including temperature, pressure and acceleration. The controller (26) is coupled to the sensors (20, 25-47), and generates a first roll condition signal as a function of the sensor signal, and generates a second roll condition signal as a function of the tire signals. The first or second roll condition signals control the rollover control system to mitigate a vehicle rollover event.
Claims22
A control system for a vehicle comprising:
- a tire sensor located within a wheel of the vehicle and generating a tire signal comprising pressure, temperature and acceleration data;
- at least one vehicle dynamics sensor generating a sensor signal;
- a rollover control system;
- and
- a controller communicating with the tire sensor and the at least one vehicle dynamics sensor, the controller generating a first roll condition signal as a function of the sensor signal, and a second roll condition signal as a function of the tire signal, the first or second roll condition signals controlling the rollover control system to mitigate a vehicle rollover event.
A control system for a vehicle comprising:
- a tire sensor located within a wheel of the vehicle and generating a tire signal comprising pressure, temperature and acceleration data;
- at least one vehicle dynamics sensor generating a sensor signal;
- a stability control system;
- at least one brake coupled to the stability control system and associated with the wheel of the vehicle;
- and
- a controller coupled to the at least one vehicle dynamics sensor and the tire sensor, the controller having a plurality of tire pressure associated brake control ranges, detecting an unstable event in response to the sensor signal and the tire signal, and applying a brake pressure in response to the tire signal and the plurality of tire pressure associated brake control ranges via the stability control system.
A control system for a vehicle comprising:
- a tire sensor located within each wheel of the vehicle and generating a tire signal comprising pressure, temperature and acceleration data;
- at least one vehicle dynamics sensor generating a sensor signal;
- a rollover control system;
- and
- a controller wirelessly communicating with each tire sensor and the at least one vehicle dynamics sensor, the controller generating a first roll condition signal as a function of the sensor signal, and a second roll condition signal as a function of the tire signal, the first or second roll condition signals controlling the rollover control system to mitigate a vehicle rollover event,
- wherein the controller generates the second roll condition signal as a function of the tire signal by comparing frequency response characteristics of the tire signal to stored frequency response characteristics indicative of a rollover event, or by comparing amplitude response characteristics of the tire signal to stored amplitude response characteristics indicative of a rollover event.
