Abstract
A method for monitoring torque produced by a motor vehicle engine, or an electric engine, including: comparing an estimated or measured value of torque produced by the engine with a low limit value or high limit value to detect excessive braking or acceleration and/or a lack of braking or acceleration; calculating the low limit value or high limit value, the calculating including: subtracting or adding a static error value to a torque value requested by a driver of the vehicle to obtain a low or high intermediate signal; and applying, to the intermediate signal, a delay corresponding to a response time of the engine to a torque increase request or to a torque decrease request expressed by the driver of the vehicle.
