Description

M288864 VIII. New description: [New technical field] This creation is a non-memory reversing controller, the principle is existing

In the vehicle electric mirror switch and the electric mirror line, a set of non-memory reversing controllers can be connected in series, and the AC signal obtained from the positive and negative poles of the electric mirror motor can be measured by the precision calculation of the microprocessor. The parameters related to the number of revolutions and the number of revolutions of the motor, plus the parameters related to the pre-measurement of the angle of the motorized mirror and the number of revolutions of the motor, and the use of the recording processor to accurately calculate the relationship between the yaw angle of the motorized mirror and the rotating circle of the motor On the contrary, the signal after reversing also starts the compensation drive circuit, which is accurately returned to the original electric mirror, and the non-memory learning reversing field of view compensation controller of the field angle u is used when the rear view mirror yaw angle is available. Computer program changes, and

The start of the reversing signal can be seen by the driver to set the driver's own characteristics. The driver's reversing habits are set, which in turn controls the angle of the electric mirrors. [Previous technology] Most of the white rearview mirrors have electric rearview mirrors that can be adjusted in the upper, lower, left and right directions. In addition, the electric rearview mirror is automatically folded when the soap dispenser is turned off. However, this private mobile rear mirror cannot automatically slant the electric mirror lens at certain angles when the vehicle is reversing. In order to overcome the dead angle on the rear sides of the reversing, there is a problem in the current electric rearview mirror. In addition, there is another "multi-segment memory type electric rearview mirror" in the market, such as Announcement No. 459673 and Announcement No. 557884. The patents are: providing a set of vehicles with a microprocessor, a memory, etc., which provide a vehicle Control the angle of the power mirror hem when turning the arm and reversing, and store the hem angle as a memory. The above-mentioned "multi-segment memory type electric rearview mirror" has some problems such as:

The internal memory is used, the starting angle position must be memorized in advance, and the sample of the angle setting must be obtained first. When installing the electric rearview mirror which is not the original factory but is a standard product, it is easy to generate memory due to the different brands. And other issues. The genus and σ are implicit. Therefore, it is necessary to additionally use the button switch to pre-synchronize and sag the hem angle. This operation is complicated and cumbersome, and the cost is high. Benefits and circuits are not suitable. This memory has the special rules for the electric rearview mirrors, so the overall electric mirrors and circuits must be replaced. This will increase the burden on the vehicle users. M288864 [New content] There is still a lack of automatic hem electric rearview mirror angles that are still present in the above-mentioned patented technology. The non-memory reversing controller of this creation solves the problem that the vehicle has the electric rearview mirror installed. No problem when reversing;

The solution lies in that the motor electric mirror switch and the electric rear view group non-memory reversing controller can connect the AC signal obtained from the positive and negative poles of a mirror motor from the motor mirror circuit through the microprocessor. fine

The parameters related to the number of revolutions and the number of revolutions of the motor are measured, and the parameters of the electric mirror angle and the number of motor turns are pre-measured, and the angle of the motor mirror hem can be accurately calculated by using the micro-processing n. The relationship between the number of motor rotations is controlled, and vice versa, the phase angle of the motorized rearview mirror can also be refined. This non-memory learning reversing field of view compensation controller can provide general vehicle simple and no replacement. The original 5 is ready, even if the equipment is dismantled in the future, the old facilities can be used, and there is no incompatibility. In other cases, the angle of the electric mirror can be changed by computer program, or this function can be opened. Let the driver set it up so that the driver can set the angle of the desired swing. M288864 The electric switch adjustment and reversing automatically control the signal of the hem angle, and the micro-point 11 is replaced by the ^ number to correctly provide the required signal state of the micro-processing. The 仏3 drive circuit 丨3 is responsible for receiving the motorized rearview mirror from the microprocessor, and then by the ##, the circuit can accurately send the stable Thunder 1 and monitor the motor rotation number, and then Control the angle of the power mirror. Ming' read Figure 2 is the flow chart of the creative work. This non-memory reversing control benefit 1 'Enter the standby state after the power is turned on. When the driver activates the electric mirror switch 2, the non-memory reversing controller 1 The signal judging loop P is automatically activated and judged whether there is a switch signal 30' from the mirror switch 2 if there is a switch signal 3. , it belongs to the driver's hand „周整, at this time, the adjustment control is delivered to the mirror switch 2, and when the signal judgment circuit (1) in the controller 1 accepts the signal from the vehicle auxiliary reverse signal, the signal judgment circuit 12 It is judged first whether the vehicle reversing signal 2 〇 has a time setting value of more than one second 'After confirming that the set value is exceeded, i ^ start switch $ signal 3 () loop 'that is, the driver cannot manually adjust the electric motor at this time The rear view mirror 3 is completely replaced by a non-memory reversing device, and the controller 1 controls the action 'At the same time, the drive circuit 13 is compensated, the electric mirror 3 is swayed to a preset angle, and the switch signal 3 is restored. At this time, the action of the switch signal 30 is resumed, so that the driver can get the M288864 to control the 'Deza p-theft mirror switch 2 for moderate fine adjustment, and when the signal judgment circuit 1 2 is 彳i, , 丨τ μ , , "When the reversing signal 20 is turned off, the switch signal 3 is turned off again" and the compensation drive circuit 13 is activated to return the electric mirror 3 to the field of view before the hem. Mirror 3 returns to the original field of view, at this time heavy New recovery switch signal 3. The loop enters the standby state again, and when the signal judging loop 12 detects that there is a reverse signal 20, it continues to monitor the reversing signal. The closing switch of the present invention is that the angle of the electric rearview mirror is used by the controller to make the hem and the reply, and τ ^ to recover the signal of the switch, which belongs to the driver's own adjustment. The purpose of the time setting in the creation of this creation can be adjusted to confirm the authenticity of the reversing signal, ^ and can be adjusted according to the driver's driving habits. t stomach can be pre-measured The angle of the power mirror hem described in this creation is the most appropriate value.
