The present invention discloses a steering road sense motor system execution unit, including: a road sense upper column assembly penetrates into an upper housing to form an interference fit, a first end of a gear shaft forms a transition fit with a steering wheel, a second end of a gear shaft passes through an inner ring of a bearing in a lower housing through a clearance fit, and a second end of the gear shaft is connected to a direct drive motor through a flexible connector; the lower housing is formed into a variable diameter structure with large ends and small middle, a pressure block hole is formed on the side wall of its small diameter section, and a bearing is fixed in its second large diameter section; a torque sensor is located in the first large diameter section, and the torque sensor collects the driver's hand force and sends it to a direct drive motor controller through a Can command; a pressure block assembly is connected in the pressure block hole; and the direct drive motor controller sequentially controls the road sense motor according to the Can command. The present invention can omit complex mechanical transmission, improve its transmission efficiency, and adopt the selective switching of the SVPWM seven-segment non-conduction time, so that the output three-phase voltage is reduced at different times, and the voltage harmonic amplitude is reduced, and the current fluctuation and torque fluctuation are suppressed.

The invention provides a method, device and equipment for controlling oil injection and a computer readable storage medium. The method comprises the steps that operation parameters of a vehicle are obtained; the Miller degree in a target air cylinder of the Miller cycle engine at the current moment is determined; the Miller degree is used for representing the intensity of the Miller cycle in the target air cylinder; based on the Miller degree and the operation parameters of the vehicle, oil injection parameters of the target air cylinder are determined through a preset oil injection control model; the oil injection parameters are used for compensating the change of the thermodynamic state in the target air cylinder caused by the Miller cycle; and a target fuel injector corresponding to the target air cylinder is controlled to execute fuel injection according to the fuel injection parameters.

Provided is a control device for an electric vehicle, which suppresses a torque variation that occurs with a change in magnetic force of a drive motor, without being affected by the performance of a clutch. A clutch (83) is disposed between a drive motor (3) in which a rotor (33) is provided with a magnetic pole made of a magnetic force variable magnet (35) and a drive wheel (4R). When the vehicle (1) is running, a first clutch control is executed in which the coupling torque of the clutch (83) is controlled to be higher than the requested torque, together with torque control. When the vehicle (1) is running and the magnetic flux control is executed, the first clutch control is changed to a second clutch control in which the coupling torque is made to coincide with the requested torque before the execution of the magnetic flux control, and the micro-slip control in which the clutch (83) is set from the coupled state to the micro-slip state is started by adding a prescribed slip torque to the requested torque.
