Embodiment Construction

[0034] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings:

[0035] Device Example:

[0036] The invention provides a vehicle wheel hub test control device, comprising a processor, an automatic gearbox, a memory, and a program stored in the memory and running on the processor. The automatic gearbox corresponds to figure 1 The second-speed gearbox in the processor corresponds to figure 1 The second-speed transmission controller (Transmission Control Unit, TCU) and the vehicle controller (VehicleControl Unit, VCU) in the second-speed transmission are connected to the second-speed transmission controller, and the second-speed transmission controller is connected to the CAN bus. CAN The bus is also connected to the vehicle controller. The vehicle controller collects and connects the gear shifter, the accelerator pedal and the brake pedal. The CAN bus is connected to the on-board instrument. The on-board ...

Abstract

The invention provides a vehicle and a vehicle wheel hub test control method and device. By collecting the wheel speed signal, the brake pedal opening signal, the accelerator pedal opening signal and the effective gear signal of the vehicle, when the wheel speed signal is zero , when the opening of the brake pedal and the opening of the accelerator pedal are both zero, the vehicle is controlled to perform at least one gear switching control according to the effective gear signal, and when the last gear control is to control the vehicle to enter the forward gear state, control the The automatic transmission is directly changed to the second gear, which solves the problem that the automatic transmission cannot switch gears during the hub test. Avoid causing the vehicle to fail to shift, so that the vehicle can normally complete the hub test.

Description

technical field [0001] The invention belongs to the technical field of vehicle gear control, and in particular relates to a vehicle and a vehicle wheel hub test control method and device. Background technique [0002] When testing a vehicle with a hub, the resistance provided by the hub is different from that provided by the road surface. At present, all cars with automatic transmissions, such as electric vehicles, basically cannot achieve automatic shifting on the hub. The automatic transmission needs to match the output speed and torque of the motor with the output speed and torque of the automatic transmission when shifting gears. On the hub, the electric vehicle needs to cut off the power during the shifting process. After the power is cut off, the electric vehicle needs to be cut off. The speed of the rear axle changes too fast, which makes it impossible to meet the conditions for gear switching. The automatic transmission determines that the gear shift fails, and the e...
