Abstract
The present embodiments relate to a vehicle control device and method, and a vehicle system. The vehicle control device may include a determinator determining a road surface condition based on vehicle driving information and determining whether to brake a vehicle based on a result of determining the road surface condition and a vehicle controller controlling a braking device according to a result of determining whether to brake the vehicle by the determinator and controlling a steering device based on control of the braking device.
Claims11
A vehicle control device, comprising:
- a processor configured to determine a road surface condition based on vehicle driving information and determine whether to brake a vehicle based on a result of determining the road surface condition;
- and
- a vehicle controller configured to control a braking device according to a result of determining whether to brake the vehicle by the processor and control a steering device based on control of the braking device,
- wherein the road surface condition includes at least one road surface condition of a split friction road surface condition or a black ice road surface condition,
- wherein the processor is configured to, if determining that the determined road surface condition is at least one of the split friction road surface condition or the black ice road surface condition, determine to brake the vehicle,
- wherein the vehicle controller is configured to control an operation of the braking device based on anti-lock braking system (ABS) control if the processor determines to brake the vehicle and control an operation of the steering device based on a counter steer control,
- wherein the vehicle controller sets an inter-vehicle distance for a smart cruise control to a maximum distance and sets a following speed of the vehicle for the smart cruise control to a road surface limit speed to control the operation of the vehicle, and
- wherein the processor is configured to, if determining that the determined road surface condition is not at least one of the split friction road surface condition or the black ice road surface condition, determine not to brake the vehicle.
