Motor vehicle driving assistance module and method

A driving assistance module for a motor vehicle, comprising:

• a main block that receives, at input, a set of input data relating to the motor vehicle and to its environment, and that provides, at output, a preliminary control setpoint for the motor vehicle based on the input data;
• and
• a safeguarding block for safeguarding the preliminary control setpoint, which safeguarding block is separate from the main block and receives, at input, the preliminary control setpoint and a set of check data, provides, at output, a final control setpoint and checks that the preliminary control setpoint is in accordance with a set of at least one predefined rule,
• wherein the set of check data differs from the set of input data, and
• wherein each of the check data has a safety level strictly higher than a safety level of at least one of the input data.

A method for computing a final control setpoint for a motor vehicle equipment, comprising:

• receiving, at a main block, a set of input data relating to the motor vehicle and to its environment;
• computing, via the main block, a preliminary control setpoint based on the input data;
• receiving, at a safeguarding block separate from the main block, the preliminary control setpoint and a set of check data;
• and
• computing the final control setpoint, which comprises checking that the preliminary control setpoint is in accordance with a set of at least one predefined rule,
• wherein the set of check data differs from the set of input data, and
• wherein the check data has a safety level strictly higher than a safety level of at least one of the input data.
