Claim 0:
1. A system to control components of a vehicle, comprising:
a data processing system comprising one or more processors and memory to:
receive, via an inertial measurement unit (“IMU”) on the vehicle that measures at a frequency of at least 100 Hertz, vertical acceleration data, angular velocity data, and lateral acceleration data;
receive, via a first range sensor on the vehicle that measures at the frequency and is located on a lateral axis of the vehicle with the IMU, first vertical displacement data corresponding to a distance between the first range sensor and a first portion of a ground that contacts a first tire of the vehicle;
receive, via a second range sensor on the vehicle that measures at the frequency and is located on the lateral axis of the vehicle with the IMU, second vertical displacement data corresponding to a distance between the second range sensor and a second portion of the ground that contacts a second tire of the vehicle;
receive, via a positioning sensor on the vehicle, location data of the vehicle and altitude data of the vehicle;
determine a vertical vehicle body height based on fusing the vertical acceleration data and the altitude data;
determine a vehicle roll angle based on fusing the vertical acceleration data, the angular velocity data, and the lateral acceleration data;
determine a first height of a first side of the vehicle and a second height of a second side of the vehicle based on a track width of the vehicle, the first vertical displacement data, the second vertical displacement data, the vertical vehicle body height, and the vehicle roll angle;
determine a road height at the location on the ground based on the first height of the first side of the vehicle and the second height of the second side of the vehicle; and
provide the road height to a controller of one or more vehicles to cause the controller to control a component of the one or more vehicles based on the road height.
