1/8
The VCU is the brain of an EV. It handles torque, energy mgmt, & regen braking. There is zeroroom for error. โก๏ธ
How do we deliver microsecond responses? Enter: Chengxuan RT-Thread Safety OS.
2/8
Chengxuan runs on an RTOS certified to ISO 26262 ASIL-D.
Not "good enough" safety. Weโre talking safety-first from the kernel to the app layer.
3/8
Key capability #1: Microsecond Interrupt Response.
Priority-preemptive scheduling means torque calculation & safety monitoring jump the queueโalways. Your foot hits the pedal, the car reacts. Instantly. โก๏ธ
4/8
Key capability #2: Deterministic Scheduling.
Control, diagnostics, commsโall running on the same hardware without stepping on each other's toes. Multi-core? We use static core binding for predictable execution.
5/8
Key capability #3: Robust IPC.
Message queues, mailboxes, semaphores. We keep data moving fast between VCU components without race conditions or deadlocks.
6/8
Safety Pillars (ASIL-D):
MPU Memory Partitioning
Timing Supervision (Alert โ Degrade โ Safe)
Static Memory (Zero malloc/free, MISRA-C)
Microsecond Failover
7/8
The result? Production-proven.
Hundreds of thousands of vehicles from Tier-1 OEMs in China are already running Chengxuan. Road-tested, not just lab-tested.
8/8
"Real-time. Deterministic. Safe."
Three words validated by hundreds of thousands of miles on the road daily.
