Abstract

A control system for a vehicle includes a safety device controller (restraint control module) to control initiation of at least one safety device in the vehicle and a brake controller to control braking in the vehicle for roll stability control. The control system includes at least one sensor operably connected to the safety device controller. The control system also includes a single angular roll rate sensor operably connected to the safety device controller and brake controller. The single angular roll rate sensor, which includes a gyroscope, is operably connected to a precision A/D converter and is configured to detect a crash event for the safety device controller and vehicle motion for the brake controller.

Claims

1. A control system for a vehicle, comprising:

a safety device controller to control initiation of a safety device in the vehicle;

a brake controller to control braking in the vehicle; and

a single angular roll rate sensor operably connected to an A/D converter such that the single angular roll rate sensor is configured to provide sufficient sensitivity for both the safety device controller and the brake controller.

2. The control system according to claim 1, wherein the angular roll rate sensor includes a gyro.

3. The control system according to claim 2, wherein the gyro is configured to include a detection rate of about ±

240 deg/sec for detecting a crash event.

4. The control system according to claim 1, wherein the single angular roll rate sensor is configured to detect vehicle motion for the brake controller.

5. The control system according to claim 1, wherein the gyro is configured to include a detection rate of about ±

80 deg/sec for detecting vehicle motion for the brake controller.

6. The control system according to claim 2, wherein the safety device controller and the brake controller together only operate with the single gyro.

7. A vehicle sensory system, comprising:

a single angular roll rate sensor;

an A/D converter connected to the angular rate sensor; and

a mechanism to connect the digital signal from the A/D converter to more than one actuation system in the vehicle.

8. The vehicle sensory system according to claim 7, wherein the angular roll rate sensor includes a gyro.

9. The vehicle sensory system according to claim 8, wherein the gyro is configured to include a detection rate of about ±

240 deg/sec for detecting a crash event.

10. The vehicle sensory system according to claim 7, wherein the single angular roll rate sensor is configured to detect vehicle motion for the brake controller.

11. The vehicle sensory system according to claim 8, wherein the gyro is configured to include a detection rate of about ±

80 deg/sec for detecting vehicle motion for the brake controller.
