The invention provides an automobile cruise control method. The automobile cruise control method includes the steps that S1, the cruise speed Vs and a cruise control transition region (Vs-Vm, Vs+Vm') are set, a control signal is input, and a cruise control mode is executed; S2, a cruise controller acquires the current automobile speed V and judges the change condition of the automobile speed, if the current automobile speed enters the cruise control transition region (Vs-Vm, Vs+Vm') from the value smaller than Vs-Vm, the cruise controller calculates the accelerator proportionality coefficient k according to a first curve, if the current automobile speed V enters the cruise control transition region (Vs-Vm, Vs+Vm') from the value larger than Vs+Vm', the cruise controller calculates the accelerator proportionality coefficient k according to a second curve, the horizontal coordinates of the first curve and the second curve are the current automobile speed V, the longitudinal coordinates of the first curve and the second curve are the accelerator proportionality coefficient k, and k ranges from 0 to 1; S3, an ECU outputs accelerator signals according to the formula of A=A0+kA1 to control the opening of a throttle. The method has the remarkable advantages that performance is safe and reliable, the structure is simple, implementation is easy, the automobile driving process is more stable, cruise control is adopted, the two feet of a driver can be released, and the hurt caused by fatigue driving is reduced.
