• The around view monitor control unit calculates the trajectory needed to move to the final parking space (tar-
get parking rectangle), and the required amount of steering rotation, and performs the following control.
- The forward/reverse starting position rectangle (green) and target parking rectangle (blue) are set based on
internal calculations and the shift position signal, and the camera image signal is transmitted to the NAVI
control unit in order to show the target position in the display.
- The target steering angle is calculated based on the vehicle speed signal, steering angle sensor signal, and
shift position signal. The system transmits the steering angle command via CAN communication to the EPS
control unit for performing steering.
- Buzzer drive signal is transmitted to the sonar control unit via CAN communication for outputting the buzzer.
- The sonar indicator display signal is received by CAN communication from the sonar control unit. If an
obstacle is present, the camera image signal is transmitted to the NAVI control unit and a warning is shown
in the display. For sonar functions, refer to
SN-124, "SONAR SYSTEM : System Description"
Operation Condition
Park Assist switch ON conditions
• The engine is started
• The around view monitor screen (top view) is displayed on the display
• The vehicle speed is less than 30 km/h (18.6 MPH) (Except reverse range/gear)
• The vehicle speed is less than 10 km/h (6.2 MPH) (Reverse range/gear)
Start switch ON conditions
• Vehicle speed is 0 km/h (0 MPH) (vehicle is completely stopped)
• Steering wheel position is straight-ahead
• Selector lever is in the D position.
The Park Assist is deactivated under the following conditions:
• When the steering wheel is operated manually
• When the shift lever is placed in the P range (CVT model).
• When 5 seconds have passed since the shift lever was placed and kept in the N range/neutral position.
• When reverse operations are conducted more than 10 times for steering corrections.
• When the system judges that the conditions (such as worn out or low pressure tires, road conditions, etc.)
are not suitable for correct course predictions.
• When the vehicle backs up to a position behind the place from which Park Assist operation started.
• When the vehicle passes the reverse starting position by over 2 m (7 ft).
• When the vehicle speed exceeds approximately 7 km/h (4 MPH).
• When the parking operation by the driver deviates from the Park Assist guidance to some extent.
OPERATION DESCRIPTION (PARALLEL PARKING)
• The sonar control unit detects parking space and performs the Park Assist.
• The sonar control unit calculates the space needed to move to the final parking space, and the required
amount of steering rotation, and performs the following control.
- The target steering angle is calculated based on the vehicle speed signal, steering angle sensor signal, and
shift position signal/shift lever position. The system transmits the steering angle command via CAN commu-
nication to the EPS control unit for performing steering.
- Outputting the buzzer.
- If an obstacle is present, the camera image signal is transmitted to the NAVI control unit and a warning is
shown in the display. For sonar functions, refer to
SN-124, "SONAR SYSTEM : System Description"
