As in the title, according to GB/T 34590, the latest version of GB 17674 puts forward mandatory functional safety requirements for automobile steering systems, as shown in the following figure:

 

I would like to ask all the big guys, are there any mature solutions and a basis for selecting relevant major chips to meet the steering system and the upcoming functional safety standards (braking, drive, thermal management)?

Regarding EPS designs that meet ASIL D, IFX recommends the electronic solutions used by IFX:

Among them, MCU, power supply, MOS drive chip, motor current sensor, motor position sensor, steering wheel torque sensor, steering wheel angle sensor and other series of supporting chips that satisfy ASIL. The specific chip selection needs to be based on specific requirements. Recommended products:

At the same time, EPS design solutions that meet the needs of autonomous driving.

For the 24V system, the power supply in the above system and the MOS driver chip need to be adjusted accordingly.
