Abstract
A driving force control apparatus includes: a sensor that collects information associated with a state of a vehicle, a driving device that provides a driving force to a drive wheel of the vehicle, and a processor electrically connected with the sensor and the driving device. In particular, the processor calculates a required driving force of a driver and a limit driving force of the vehicle based on at least a portion of information collected by means of the sensor, in a situation where the vehicle is turning. The processor further controls the driving device such that the required driving force does not exceed the limit driving force.
Claims16
A driving force control apparatus, comprising:
- a sensor configured to collect information associated with a state of a vehicle;
- a driving device including at least one of an engine or a motor and configured to provide a driving force to a drive wheel of the vehicle;
- and
- a processor electrically connected with the sensor and the driving device,
- wherein the processor is configured to:
- calculate a required driving force of a driver based on at least a portion of information collected by the sensor, in a situation where the vehicle is turning;
- calculate a limit driving force based on (i) a minimum value between a maximum driving force of a left drive wheel and a maximum driving force of a right drive wheel tire of the vehicle, and (ii) an estimated lateral force for a tire of the vehicle;
- compare the required driving force with the limit driving force;
- calculate a braking force when the required driving force exceeds the limit driving force;
- and
- provide the calculated braking force to a braking device,
- wherein the limit driving force corresponds to a maximum driving force at which the vehicle maintains lateral stability while the vehicle is turning.
A vehicle system, comprising:
- a manipulation device including a steering input device, an acceleration input device, and a brake input device;
- and
- a driving force control apparatus electrically connected with the manipulation device,
- wherein the driving force control apparatus is configured to:
- collect information associated with a state of a vehicle in a situation where the vehicle is turning and calculate a required driving force of a driver based on at least a portion of the collected information;
- calculate a limit driving force based on (i) a minimum value between a maximum driving force of a left drive wheel and a maximum driving force of a right drive wheel tire-of the vehicle, and (ii) an estimated lateral force for a tire of the vehicle;
- compare the required driving force with the limit driving force;
- calculate a braking force when the required driving force exceeds the limit driving force;
- and
- provide the calculated braking force to a braking device,
- wherein the limit driving force corresponds to a maximum driving force at which the vehicle maintains lateral stability while the vehicle is turning.
An operation method of a driving force control apparatus, the operation method comprising:
- collecting information associated with a state of a vehicle, in a situation where the vehicle is turning;
- calculating a required driving force of a driver and a limit driving force of the vehicle based on at least a portion of the collected information;
- calculating a limit driving force based on (i) a minimum value between a maximum driving force of a left drive wheel and a maximum driving force of a right drive wheel tire-of the vehicle, and (ii) an estimated lateral force for a tire of the vehicle;
- comparing the required driving force with the limit driving force;
- calculating a braking force when the required driving force exceeds the limit driving force;
- and
- controlling the driving force control apparatus to reduce a driving force of the vehicle based on the calculated braking force or providing the calculated braking force to a braking device,
- wherein the limit driving force corresponds to a maximum driving force at which the vehicle maintains lateral stability while the vehicle is turning.
