Control method for wheel hub motor type hybrid electric vehicle

Abstract

The invention discloses a wheel hub motor type hybrid electric vehicle. Both sides of a vehicle rear axle are respectively provided with a carbon brush group. A clutch is arranged between a shell and a rear axle of the wheel hub motor. An axle braking device is mounted on the rear axle. A magnetic induction wheel speed sensor is installed beside each wheel. A gear control device is arranged on an automatic transmission vehicle. Signals of the magnetic induction wheel speed sensors, a steering sensor, a front camera, a front radar, a rear camera, a rear radar, a satellite navigator, a throttle detection device, a brake pedal detection device and the like are input into a wireless internet access computer; and output control lines of the wireless internet access computer are respectively connected to a main controller and a special controller. Output lines of the special controller are respectively connected to a motor controller, an energy recovery converter, an electronically controlled clutch or a hydraulic clutch, the gear control device, the axle braking device, an electric oil pump and the like. An output line of the motor controller is connected to the wheel hub motor, and an output line of the energy recovery converter is connected to an energy recovery relay battery and a storage battery.

Description

Technical field: [0001] The invention relates to a control method of a wheel hub motor type hybrid electric vehicle with an automatic driving function of the hybrid electric vehicle. Background technique: [0002] Application No. 2011100466154 "In-wheel motor hybrid vehicle based on traditional vehicle transformation" patent application pointed out that the hybrid vehicle includes traditional vehicles and the addition of accelerator and brake pedal position detection devices, special controllers, motor controllers, A special control system composed of energy recovery relay battery, energy recovery converter, language prompter, gear detection device, power steering device, etc. An electric oil pump is added, and the hubs of the four wheels use disc permanent magnet brushless DC double-acting hub motors. The hybrid electric vehicle has three working modes: a pure electric working mode, a pure engine working mode and a hybrid working mode. The so-called pure electric working ...

Problems solved by technology

At present, the price of plug-in hybrid electric vehicles after the national subsidy plus the cost of fuel saving within the service life is still greater than the price of ordinary cars plus the fuel cost of ordinary cars within the service life; that is, the purchase of plug-in hybrid car is not worth it
