Embodiment Construction

[0009] Such as figure 1 After connecting the ECU to the test cabinet as shown, adjust the connection between the host and the test cabinet, and establish the target model on the host to ensure that the target model runs normally in simulink simulation, modify the target model, and establish a model suitable for hardware-in-the-loop , and then model configuration, select the xpctarget.tlc or xpctargetert.tlc configuration file; select fixed-step in the solver, and select the default configuration for other configurations. Remove automatically download application after building in xPC Target options. Build the target model.

[0010] The monitoring software is also operated on the host. Before operating the software, first ensure that the host is connected to the target machine of the functional test bench with a network cable; secondly, connect the simulated load or real load device according to the actual needs of the test; ECU; start the target machine of the function te...

Abstract

The invention relates to an ECU (Engine Control Unit) hardware in-the-loop test board and a control method thereof. The ECU hardware comprises a target machine, a host machine, a data acquisition card, an interface circuit board, a measuring board and a simulating load device. Monitoring software has the following functions of: (1) downloading a target program.d1m file to the target machine and controlling the running and stopping of the target program; (2) establishing a virtualized driver operating platform; (3) observing, collecting and archiving data of the real-time target program; (4) modifying running parameters of the real-time program; and (5) choosing a running condition of an engine.

Description

technical field [0001] The invention relates to a design method of an ECU hardware-in-the-loop test bench, in particular to a design method of software and hardware. Background technique [0002] The ECU function test bench is used for the function test of the vehicle controller, simulating the driving state of the vehicle in various working conditions on the actual road, and realizing the simulatable or selectable and accurate output of the correct information to the vehicle controller under various working conditions. The signal can display the real-time status of the controller; at the same time, it can truly simulate the input signal of the vehicle controller, and the user can program the input signal; in addition, the test platform has an open software and hardware environment, and has strong scalability and compatibility. sex. [0003] Hardware-in-the-loop simulation (HIL) is a powerful test method that can be used to test embedded control systems more effectively. Wh...
