3 Terms and Definitions
For the purposes of this Standard, the terms and definitions given in GB/T 5179 and
the following apply.
3.1 Controller working properly
The automobile electric power steering device (hereinafter referred to as device) shall
be installed on the test bench; the controller, motor and sensor are normally connected;
the whole vehicle signal is normally input. After the power is turned on, rotate the
steering wheel device left and right to assist normally.
3.2 Controller failure
The controller is considered invalid in case one of the following conditions:
a) During the function test, due to the controller, there is non-smooth, stuck, obvious
4.1.4.1 Nominal voltage: 12V or 24V.
4.1.4.2 The allowed voltage change range:
a) 9V ~16V (nominal voltage of 12V)
b) 20V ~ 32V (nominal voltage of 24V).
4.1.5 Self-test function and fault code.
The controller shall have self-test function, and can store the fault code.
4.2 Performance
4.2.1 Function.
During the process of manually rotating the steering wheel at different speeds, it shall
be smooth, without stuck or obvious inertia delay.
4.2.2 Power current characteristics.
At different speeds, the relationship between the input torque and the output current,
i.e. the power current characteristics, shall meet the manufacturer’s requirements. The
symmetry of the curve at each vehicle speed (allowed to be represented by 0 km/h
speed) shall be ≥ 90%.
4.2.3 Failure alarm.
The controller shall have the function of failure alarm. When the motor, sensor and the
entire vehicle input signal are detected to be abnormal or controller itself fails, the
controller shall output the fault alarm signal. In the event of any fault, the mechanical
part of the device shall work properly.
4.2.4 Resistance to power supply voltage fluctuation.
The controller shall have the ability to adapt to fluctuations for the power supply voltage.
When the vehicle power supply changes within the range of 9V ~ 16V (nominal voltage
of 12V) or 21.6V ~ 32V (nominal voltage of 24V), the controller shall work properly.
After the test, the variation of the power current characteristics shall be < 15%.
4.2.5 Reverse connection of power supply and voltage overload.
The controller shall have the ability to resisting the reverse connection of power supply
and voltage overload. After test, the controller can work properly.
4.2.6 Drop.
After the drop test, the controller shall work normally; and meet the requirements of
After the test, the controller can work properly, and m...
