Background of ECU Testing
ECU measurement background with the development of automotive technology, the car more and more places to use the computer control, the computer relies on a variety of data transmitted back to the sensor to understand the car situation, and make corresponding responses to the car situation, so as to control a variety of actuators. However, in reality, the car often encountered complex and harsh conditions, which requires the development of the ECU process to take into account a variety of situations and make corresponding countermeasures to protect the safety of passengers and the normal operation of the car!
ECU Testing Difficulties
ECU research and development is often done in the laboratory, which leads to a difficult problem, how to simulate the complex and changing real-world conditions in the laboratory, and to achieve the fastest possible switching of various states, so as to detect the algorithm's response in different situations in a short period of time. Traditional simulation means such as the temperature chamber has a large volume of equipment, state switching is not flexible enough to quickly and other shortcomings, for example, temperature is a simulation of a quantity, the speed of its change is too slow, from one temperature to another temperature need to wait for a long time, which seriously slows down the R & D process. At the same time there is also a need to simulate some of the physical aspects of the sensor failure, such as the sensor in the harsh environment of the short-circuit, short-circuit and other faults, we need to car computers in the event of sensor failure can not be down to maximize the protection of the passenger's safety, but if we want to simulate these faults in the laboratory, it means a lot of manual operation and some destructive experiments.
Honghong Automobile ECU Fault Injection System
In our system, through the simulation of the sensor signal, to achieve a kind of ECU “deception”, the use of sensor simulation board to send to the ECU a certain kind of sensor exactly the same signal, can be done to let the ECU work normally, but at the same time we have a flexible control of the board, can be set at any time to any state, so as to We have flexible control over the board, which can be set to any state at any time, so that it can be quickly switched between different environmental conditions. At the same time, we use a programmable fault injection board, which can simulate the damage of various sensors at the physical level with one click, without having to manually unplug the wires and destroy the real thing. We also equipped with CAN bus simulation board, can simulate the CAN bus node. Through the whole system, we can quickly and accurately allow the ECU to sense various driving conditions and external environment, so as to quickly and accurately detect the algorithms therein.
