Abstract
A user input signal management method for a vehicle provided with a prime mover having an output that rotates and an input for a user input signal that controls the rotating speed of the output of the prime mover. The method including the reception of a signal representative of the position of a user input of a vehicle, the reception of data representative of at least one condition of the vehicle, the modification of the received signal representative of the position of the user input as a function of the data received and the supply of the modified signal to the accelerator input of the prime mover.
Claims20
A user input signal management method for a vehicle provided with a drivetrain including a prime mover having an output that rotates and an input that controls a rotating speed of the output of the prime mover, the drivetrain further including a user input, the method comprising:
- receiving a user input control signal representative of a position of the user input of the vehicle;
- receiving data representative of at least one condition of the vehicle;
- generating a max point signal as a function of the data received;
- determining a lesser signal of the control signal and the max point signal;
- and
- supplying the lesser signal to the input of the prime mover.
A user input signal management method for a vehicle provided with a drivetrain including a prime mover having an output that rotates and an Engine Control Unit (ECU) having first and second inputs, the vehicle also including a user input, the method comprising:
- supplying a user input control signal representative of a position of the user input of the vehicle to the first input of the ECU;
- receiving data representative of at least one condition of the vehicle;
- generating a max point signal as a function of the data received;
- and
- supplying the max point signal to the second input of the ECU;
- wherein the prime mover rotates the output at a speed that is a function of a lesser signal of the user input control signal and the max point signal.
A drivetrain for a vehicle provided with a user input including an output configured to generate a control signal representative of a position of the user input, the drivetrain comprising:
- a prime mover provided with an output and with an Electronic Control Unit (ECU) having an input;
- the ECU configured to rotate the output of the prime mover at a speed that is a function of a signal received at the input thereof;
- and
- a controller having an input connected to the output of the user input to receive the control signal therefrom, at least another input allowing vehicle condition data to be supplied to the controller;
- the controller configured to generate a max point signal as a function of the vehicle condition data;
- the controller having an output connected to the input of the ECU of the prime mover;
- the controller being so configured as to supply a lesser of the control signal and the max point signal to the user input of the ECU.
A drivetrain for a vehicle provided with a user input so configured as to generate a control signal representative of a position of the user input, the drivetrain comprising:
- a prime mover provided with an output and with an Electronic Control Unit (ECU) having first and second inputs;
- the first input receiving the control signal from the user input;
- and
- a controller having at least one input allowing vehicle condition data to be supplied to the controller;
- the controller configured to generate a max point signal as a function of the vehicle condition data;
- the controller supplying the max point signal to the second input of the ECU;
- the prime mover configured to rotate the output of the prime move at a speed that is a function of a lesser of the control signal and the max point signal.
