Performance requirements and test methods for intelligent
parking assist system
1 Scope
This document specifies the general requirements, performance requirements and test
methods for intelligent parking assist system.
This document is applicable to M1 vehicles equipped with intelligent parking assist
system. Other types of vehicles can use this document as reference for the
implementation.
2 Normative references
The following referenced documents are indispensable for the application of this
document. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.

compatibility
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 intelligent parking assist system; IPAS
A system that automatically detects the parking space and provides the driver with
auxiliary functions such as parking instructions and/or directional control when the
vehicle is parked.
NOTE 1: Direction control includes lateral control or lateral and longitudinal combined control.
NOTE 2: Parking space may also be referred to as "parking slot".
NOTE 3: The intelligent parking assist system is hereinafter referred to as the "system".
3.2 vehicle undertest
4.2 System status transition and information prompt
4.2.1 System inactive status
The system inactive status includes the off status and the standby status. In this status,
the system shall not control the vehicle.
4.2.2 Slot search status
4.2.2.1 The system shall switch from the inactive status to the working status of slot
search in at least one of the following ways:
a) Active activation: The driver actively activates the slot search status mode;
b) Automatic activation: When the vehicle speed reaches a certain threshold, it will
automatically enter the slot search status mode.
4.2.2.2 The system shall have the ability to search for parking slot and be able to search
for at least one of the following types of parking slots:
a) Category 1 IPAS parking slots are parking slots enclosed by bordering vehicles;
b) Category 2 IPAS parking slots are parking slots enclosed by parking slot defining
line.
4.2.2.3 The system shall prompt the parking slot information through the driver's active
confirmation or automatic display.
4.2.3 Assisted parking status
4.2.3.1 The initial condition for the system to enter the assisted parking status shall be
that the vehicle is stationary. When the driver actively confirms the position of the
parking slot, the system shall switch to the assisted parking status.
4.2.3.2 The system shall have at least one of the following control modes to assist the
driver to park the vehicle in the parking slot:
a) Lateral control mode: The system controls the lateral movement of the vehicle.
The driver controls the longitudinal movement of the vehicle;
b) Lateral and longitudinal combined control mode: The system controls the lateral
and longitudinal movement of the vehicle.
4.2.3.3 In the assisted parking status, the system shall send out status and operation
information prompts and set the maximum running speed not greater than 10km/h.
When the vehicle speed exceeds the maximum driving speed, the system shall send a
prompt message to the driver and exit the assisted parking status.
4.2.3.4 After the system completes the assisted parking control, it shall send a prompt
message to the driver and exit to the inactive status.
4.2.4 System exit conditions
In the assisted parking status, the system shall have the function of taking over the
control of the vehicle at any time and exiting to the inactive status through the driver's
active way. The driver's active exit conditions are described in the system manual. Exit
conditions may include, but are not limited to, the following:
- Operate the steering wheel;
- Operate the brake pedal;
- Operate the gear;
- Operate the parking brake.
4.2.5 System failure response
If a fault occurs during system self-inspection and operation, the system shall at least
optically prompt the driver with fault information. It can exit to the inactive status.
4.3 Functional safety
The system shall comply with the functional safety requirements of Annex A.
4.4 Electromagnetic compatibility
The electromagnetic compatibility of the system shall meet the requirements of GB
34660.
5 Performance requirements
5.1 Slot search
5.1.1 Category 1 IPAS slot search
Test according to 6.2.1. The system shall search for a parking slot in the slot search
status.
5.1.2 Category 2 IPAS slot search
Test according to 6.2.2. The system shall search for a parking slot in the slot search
status.
5.3 Test criteria
5.3.1 Test of category 1 IPAS parking slots
Repeat the test according to the test group of 6.2.1. Each of the 6 groups of test items
shall be repeated 3 times. At least 2 times shall meet the corresponding requirements of
5.1 and 5.2. If a collision occurs during any group of tests, the test is judged to have
failed.
5.3.2 Test of category 2 IPAS parking slots
Repeat the test according to the test group of 6.2.2. Each of the 8 groups of test items
shall be repeated 3 times. At least 2 times shall meet the corresponding requirements of
5.1 and 5.2. If a collision occurs during any group of tests, the test is judged to have
failed.
6 Test methods
6.1 Test environment requirements
The test environment shall meet the following requirements:
a) The wind speed does not exceed 7.9m/s. The relative humidity is less than 95%.
There is no rain, snow, fog and so on;
b) The test pavement is a level (slope less than 1%), smooth, dry, concrete or asphalt
pavement with good adhesion;
c) The ambient illuminance of the target parking slot is not less than 100lx;
d) There are no interferences that affect the sensor's operation.
If category 2 IPAS test is carried out, in addition to meeting the above requirements,
the parking slot defining line shall be free of damage and clearly visible.
