In step 201, based on receiving a regeneration request signal from the diagnostic apparatus, an ECU regeneration request state is set in a control strategy code for implementing regeneration of the particulate matter trap.

For example, the diagnostic device may detect whether the vehicle's particulate matter trap needs regeneration, and upon receiving a determination of regeneration from the diagnostic device, the diagnostic device may send a regeneration request signal to the vehicle. Based on the vehicle receiving the regeneration request signal from the diagnostic apparatus, the vehicle control system controls the ECU regeneration request state in the policy code to be set and sends a regeneration request to the HCU.

Illustratively, the vehicle controls the process of particulate matter trap regeneration through a strategy code. Wherein the policy code includes an ECU regeneration request state and an HCU regeneration prohibition state. When the ECU regeneration request state is set, the ECU sends a regeneration request to the HCU; when the ECU regeneration request status clears, the ECU stops sending regeneration requests to the HCU. When the HCU regeneration prohibition state is set, the HCU does not respond to the regeneration request of the ECU; when the HCU regeneration disabled state is cleared, the HCU responds to the regeneration request of the ECU.

For the purpose of stereo acquisition or noise reduction, a plurality of microphones can be respectively arranged at different parts of the terminal. The microphone may also be an array microphone or an omni-directional pickup microphone. The speaker is used to convert electrical signals from the processor 1501 or the radio frequency circuit 1504 into sound waves. The speaker may be a conventional thin film speaker or a piezoelectric ceramic speaker. When the speaker is a piezoelectric ceramic speaker, not only the electric signal can be converted into a sound wave audible to humans, but also the electric signal can be converted into a sound wave inaudible to humans for ranging and other purposes. In some embodiments, the audio circuit 1507 may also include a headphone jack.

The acceleration sensor 1510 may detect the magnitudes of accelerations on three coordinate axes of a coordinate system established with a terminal. For example, the acceleration sensor 1510 may be used to detect components of gravitational acceleration in three coordinate axes. The processor 1501 may control the display screen 1505 to display the user interface in either a landscape view or a portrait view based on the gravitational acceleration signal collected by the acceleration sensor 1510. The acceleration sensor 1510 may also be used for acquisition of motion data of a game or user.

The gyro sensor 1511 may detect a body direction and a rotation angle of the terminal, and the gyro sensor 1511 may collect a 3D motion of the user to the terminal in cooperation with the acceleration sensor 1510. The processor 1501, based on the data collected by the gyro sensor 1511, may implement the following functions: motion sensing (e.g., changing UI according to a tilting operation by a user), image stabilization at shooting, game control, and inertial navigation.

The pressure sensor 1512 may be disposed on a side frame of the terminal and/or below the display 1505. When the pressure sensor 1512 is disposed on a side frame of the terminal, a grip signal of the terminal by the user may be detected, and the processor 1501 performs a left-right hand recognition or a quick operation according to the grip signal collected by the pressure sensor 1512. When the pressure sensor 1512 is disposed at the lower layer of the display screen 1505, the processor 1501 controls the operability control on the UI interface according to the pressure operation of the user on the display screen 1505. The operability controls include at least one of a button control, a scroll bar control, an icon control, and a menu control.

The optical sensor 1513 is used to collect the ambient light intensity. In one embodiment, processor 1501 may control the display brightness of display screen 1505 based on the intensity of ambient light collected by optical sensor 1513. Specifically, when the ambient light intensity is high, the display brightness of the display screen 1505 is turned up; when the ambient light intensity is low, the display luminance of the display screen 1505 is turned down. In another embodiment, the processor 1501 may also dynamically adjust the shooting parameters of the camera assembly 1506 based on the ambient light intensity collected by the optical sensor 1513.

A proximity sensor 1514, also referred to as a distance sensor, is typically provided on the front panel of the terminal. The proximity sensor 1514 is used to collect the distance between the user and the front face of the terminal. In one embodiment, when the proximity sensor 1514 detects a gradual decrease in the distance between the user and the front face of the terminal, the processor 1501 controls the display 1505 to switch from the on-screen state to the off-screen state; when the proximity sensor 1514 detects that the distance between the user and the front face of the terminal gradually increases, the processor 1501 controls the display screen 1505 to switch from the off-screen state to the on-screen state.
