Method for detecting measurement errors in the angle of inclination of a two-wheeled vehicle

A method for detecting measurement errors in the lateral angle of inclination (θ) of a motorized two-wheeled vehicle (1), said vehicle (1) comprising an engine (10) and an electronic control unit (11), said electronic control unit (11) comprising an inclination sensor (111) and a memory zone (112), said memory zone (112) comprising reference inclination ranges, said electronic control unit (11) being configured to compute the lateral angle of inclination (θ) of the vehicle (1) based on the measurements of the inclination sensor (111), to compare the measured angle of inclination (θ) with a predetermined inclination threshold (θs) and to send a command to stop the engine (10) if the computed angle of inclination (θ) is greater than the inclination threshold (θs), said method comprising the steps of:

• activating (E1) the electronic control unit (11) through an action by a user of the vehicle (1);
• in a first phase, the electronic control unit (11) checking (E3) that the engine (10) of the vehicle (1) is stopped;
• if the engine (10) is stopped, the electronic control unit (11) comparing (E6) the measurements of the inclination sensor (111) relative to the at least one reference inclination range;
• if the electronic control unit (11) determines that the measurements of the inclination sensor (111) are outside the reference range, detecting an error in the measurement of the angle of inclination (θ) and the electronic control unit (11) deactivating the sending of the command to stop the engine (10) according to the angle of inclination (θ) of the vehicle (1) and warning the user;
• in a second phase, starting (E7) the engine (10) of the vehicle (1) through an action by a user of the vehicle (1), and the electronic control unit (11) receiving notification of the engine (10) starting;
• the electronic control unit (11) computing (E8) the variation in the measurements of the inclination sensor (111) when the engine (10) is running;
• if the variation in the measurements of the inclination sensor (111) is below a predetermined threshold for a predetermined duration, detecting (E9) an error in the measurement of the angle of inclination (θ) and the electronic control unit (11) deactivating the function for stopping the engine (10) according to the angle of inclination (θ) of the vehicle (1) and warning the user.
