Abstract
A rollover risk assessment system includes sensors and a processor for estimating rollover risk associated with maneuvering on varying terrain.
Claims40
A vehicle rollover risk assessment system comprising:
- a processor;
- a GNSS receiver that provides vehicle position and speed information to the processor;
- pitch, roll and yaw sensors that provide vehicle attitude information to the processor;
- a three-axis accelerometer that provides vehicle acceleration information to the processor;
- a steering sensor that provides vehicle wheel angle information to the processor;
- wherein, the processor uses the position, attitude, acceleration, and wheel angle information to estimate vehicle rollover risk.
