Claims

[Scope of utility model registration request]

means for detecting engine load via accelerator opening;
comprising means for detecting the vehicle speed, and determining means for determining whether or not to shift by comparing the gear position calculated based on the input signals from both of these detecting means and the detected shift position signal,
In a vehicle automatic transmission device that performs a shift change based on the output signal of the determination means, the engine rotation speed signal from the engine speed detection means and the accelerator opening signal from the engine load detection means are each less than a set value. 1. An automatic transmission device for a vehicle, comprising a shift down control means for canceling a determination signal of the determination means and outputting a shift down operation command when
