Vehicle control system and method on low friction road

A vehicle control system for inhibiting repetitive gear shifts while a vehicle is running on a low friction road, the vehicle control system comprising:

• one or more sensors configured to detect an engine speed of the vehicle, a temperature of an engine oil, a position of an accelerator pedal, a lateral acceleration of the vehicle, a rotational angle of a steering wheel, or whether a low friction road running mode switch is turned on or off;
• and
• a controller configured to:
• receive detected data from the one or more sensors,
• determine whether the vehicle satisfies an entry condition for performing a repetitive shift prevention control based on the received data of the vehicle, and
• control a gear shift of a transmission and an engine torque of the vehicle to perform the repetitive shift prevention control when a downshift occurs in a state where the vehicle has satisfied the entry condition,
• wherein the controller comprises:
• an entry condition determinator configured to determine whether the vehicle has satisfied the entry condition or whether the entry condition has been released during the running of the vehicle based on the data received from the one or more sensors;
• a shift controller configured to inhibit the gear shift of the transmission when the downshift occurs, after the entry condition has been satisfied;
• and
• an engine torque controller configured to request an engine torque limitation when the downshift occurs, after the entry condition has been satisfied.
