Abstract
The invention provides a hydroplaning detection method and system. Hydroplaning of a tire is detected based on radial acceleration data of a tire. The radial acceleration data is obtained by using a tire-mounted sensor unit. The lightweight implementation of the method and system allows for quick and robust detection of hydroplaning at an early stage, thereby improving the overall security of a vehicle equipped with the system.
Claims20
A computer implemented method for detecting hydroplaning of a tire supporting a vehicle, comprising:
- obtaining radial acceleration data from a tire-mounted sensor unit, wherein the radial acceleration data provides an indication of the evolution of the tire's radial acceleration while the tire is rolling on a ground surface;
- and
- generating a hydroplaning detection signal based on the radial acceleration data.
A hydroplaning detection system comprising:
- a vehicle;
- a tire supporting the vehicle;
- a sensor unit being mounted on the tire, the sensor unit including a radial acceleration sensor to measure radial acceleration data while the tire is rolling on a ground surface;
- a memory element storing at least part of the acceleration data;
- and
- a processor in electronic communication with the sensor unit and with the memory element, the processor being configured to obtain radial acceleration data from the memory element, and to generate a hydroplaning detection signal based on the radial acceleration data.
A tire comprising a sensor unit attached to an innerliner of the tire, the sensor unit including a radial acceleration sensor to measure radial acceleration data while the tire is rolling on a ground surface, and a memory element in electronic communication with the sensor unit, to store at least part of the acceleration data.
