Vehicle and method for compensating for a start of the vehicle
By controlling the clutch and calculating the target engine speed compensation amount according to different states in the vehicle start-up compensation method, the problem of insufficient low-speed torque output of the engine under high load conditions on steep slopes is solved, thus achieving smooth vehicle start-up and improved climbing ability.

Abstract
This application discloses a vehicle and its starting compensation method, relating to the field of vehicle technology. The method includes: determining a starting compensation state; when the starting compensation state is a first slope starting compensation state, controlling the clutch to be in an open state, and determining a first target engine speed compensation amount based on the throttle opening signal, slope resistance torque, and the engine speed stored at the start of the start; when the slope starting compensation state is a second slope starting compensation state, controlling the clutch to be in a closed state, and determining a second target engine speed compensation amount based on the throttle opening signal and slope resistance torque; and compensating the engine speed according to the first or second target engine speed compensation amount. Thus, by activating the slope starting compensation function, the vehicle reduces the clutch engagement at low engine speeds, and the clutch quickly engages to achieve starting once the engine speed reaches the target speed, improving the vehicle's climbing ability.
