The invention relates to a control method and device for hill starting of a vehicle. The method comprises the steps that when it is recognized that a current vehicle is located on a ramp and a starting instruction is received, the current gradient and the current attachment coefficient under the current weather are obtained; according to the current gradient and the current adhesion coefficient, the minimum driving torque needed by the current vehicle is obtained; when the current driving torque indicated by the starting instruction is smaller than the minimum driving torque, a current ramp compensation coefficient is determined; and the final driving torque is obtained according to the current ramp compensation coefficient and the current driving torque, and the current vehicle is controlled to start according to the final driving torque. By adopting the method, the driving experience of the user in the prior art can be improved.
