The invention relates to a method for controlling in real time the path of a motor vehicle travelling in a traffic lane, comprising steps of: - detecting a corner in the traffic lane, then, when the motor vehicle enters said corner, - determining a first quantity and a second quantity for a plurality of successive sampling increments, on the basis of state variables characteristic of the movement of the motor vehicle, - determining a first stored value and a second stored value, said first stored value being dependent on the first quantity determined in the current sampling increment and on first quantities determined for at least one of the preceding sampling increments, said second stored value being dependent on the second quantity determined in the current sampling increment and on second quantities determined for at least one of the preceding sampling increments, - saving in memory said first stored value and second stored value determined for each sampling increment, then, when the motor vehicle exits said corner: - determining a value of the understeer gradient depending on said first stored value and second stored value saved in memory, and - determining a command for the motor vehicle on the basis of the value of the understeer gradient thus determined.
