The invention also provides a control method of the novel intelligent external rearview mirror, which comprises the following steps:
step 1, a data acquisition unit acquires a vehicle steering lamp signal in real time, and further acquires a steering wheel corner when the steering lamp signal is triggered;
step 2, judging whether the vehicle enters a steering working condition or not by the data processing unit, if the steering wheel rotating angle is larger than a preset value and the steering lamp and the steering wheel rotating angle need to be in the same direction, enabling the vehicle to enter the steering working condition and need to turn over the corresponding outer rearview mirror, and calculating a turning compensation angle needed by the corresponding outer rearview mirror according to the steering wheel rotating angle;
step 3, the execution unit energizes the motor of the exterior rearview mirror in the designated direction and controls the corresponding exterior rearview mirror to turn outwards and transversely according to the turning compensation angle;
and 4, when the turning lamp is turned off or the steering wheel returns to the right state, the vehicle is turned over, and the executing unit controls the reversed motor of the exterior rearview mirror to be electrified reversely, so that the exterior rearview mirror returns to the initial angle.
The invention has the beneficial effects that:
the invention can realize automatic adjustment of the visual field range under the working conditions that the vehicle driving postures such as vehicle starting, lane changing and steering form a certain angle with the front road and the rear road, ensure that a driver can still observe the conditions of other vehicles on the normal road, and reduce the influence of vehicle blind areas. Meanwhile, the automatic control can ensure that the driver does not need to manually change the visual angle range, so that the attention of the driver is always focused on the driving of the vehicle, the surrounding conditions of the vehicle can be known at any time, and the driving safety is improved.

Detailed Description
The technical scheme of the invention is described in detail in the following with reference to the attached drawings and embodiments:
the invention provides a novel intelligent exterior rearview mirror, which comprises a left exterior rearview mirror, a right exterior rearview mirror and a control module, wherein the left exterior rearview mirror and the right exterior rearview mirror are electrically connected with the control module, and the control module is in communication connection with a vehicle-mounted controller; the control module comprises a data acquisition unit, a data processing unit and an execution unit, wherein the data acquisition unit acquires steering wheel corner signals of the vehicle steering lamp annunciator in real time and sends the steering wheel corner signals to the data processing unit, the data processing unit judges the steering requirements of the vehicle according to the steering lamp signals and the steering wheel corners and calculates the required turnover compensation angle corresponding to the outer rearview mirror, and the execution unit controls the corresponding outer rearview mirror to turn, maintain the angle and reversely rotate according to the calculation result of the data processing unit.
The control module may be provided separately or integrated with other control modules of the vehicle.
The invention adds a control module on the basis of the original electrically-adjusted outside rear-view mirror, and identifies the steering requirement of the vehicle by acquiring a steering lamp signal, a steering wheel corner signal and the like in real time through a data acquisition unit, when the vehicle is identified to be in a steering working condition, the compensation turning angle of the left and right outside rear-view mirrors is calculated through a data processing unit, the turning angle of the corresponding outside rear-view mirror is adjusted through an execution unit, and the vehicle is kept for a certain time after the requirement of the view angle is met until the vehicle finishes steering, and the rear-view mirror is adjusted to the original angle.
A control method of a novel intelligent external rearview mirror comprises the following steps:
