Abstract
An acceleration detection system for a vehicle includes at least one inertial measurement unit, which includes at least one acceleration sensor configured for measuring an acceleration of the vehicle. The acceleration detection system further includes a temperature sensor configured for measuring a temperature of the inertial measurement unit to obtain a measured temperature. A cooler is configured for cooling the inertial measurement unit in function of the measured temperature.
Claims9
An acceleration detection system for a vehicle comprising:
- at least one inertial measurement unit comprising at least one acceleration sensor configured for measuring an acceleration of the vehicle;
- a temperature sensor configured for measuring a temperature of the inertial measurement unit to obtain a measured temperature;
- a cooler configured for cooling the inertial measurement unit as a function of the measured temperature;
- and
- a controller configured to receive a signal comprising the measured temperature, wherein the controller is configured for determining a maximum operation time of the inertial measurement unit, during which the inertial measurement unit presents a measurement deviation smaller than or equal to a measurement deviation threshold, wherein the controller is configured for determining said maximum operation time in function of said signal comprising the measured temperature.
