Overview

The purpose of this Python 3 program is to provide basic validation that the vehicle and OSCC are in a good state and are able to communicate as expected. Ideally it's a method to quickly verify whether your vehicle is in a good state. By sending control commands on the CAN gateway then polling for an expected result there, we should be able to tell whether OSCC is functioning properly or diagnose any issues more readily.

While this program was designed to be run as a stand alone executable it may be imported as a module should a use-case arise.

Prerequisites for success:

• A vehicle with OSCC installed
• That vehicle powered on (motor on)
• OSCC powered
• A socketcan connection to OSCC's CAN bus from your computer

But what does it do?

1. Enable each OSCC module (brake, steering, throttle).
2. Send commands to increase and decrease brake pressure.
3. Verify that brake pressure reported by vehicle increased or decreased accordingly.
4. Send commands to apply positive or negative torque to steering wheel.
5. Verify that the steering wheel angle increased or decreased accordingly.
6. Disable each OSCC module.

Getting Started

Compatibility

Works with OSCC v1.2.1 and up.

Linux Dependencies

• python3 (sudo apt install python3)

Windows Dependencies

• python3 (https://www.python.org/downloads/windows/)
• CAN driver (Kvaser, PCAN, etc.)

Building

Install this package's dependencies with the following command:

python3 setup.py install --user

Usage

oscc-check.py (-V <vehicle>) [-hdelv] [-b <bustype>] [-c <channel>]

Options

Options:
    -h --help                            Display this information
    -V <vehicle>, --vehicle <vehicle>    Specify your vehicle. Required.
                                         (kia_soul_ev / kia_soul_petrol / kia_niro)
    -d --disable                         Disable modules only, no further checks (overrides enable)
    -e --enable                          Enable modules only, no further checks
    -l --loop                            Repeat all checks, run continuously
    -b --bustype <bustype>               CAN bus type [default: socketcan_native]
                                         (for more see https://python-can.readthedocs.io/en/2.1.0/interfaces.html)
    -c <channel>, --channel <channel>    Specify CAN channel, [default: can0]
    -v --version                         Display version information

Usage Notes

Linux

On a Linux system socketcan is a default so the oscc-check.py can rely on the default settings for bustype and channel. After initializing the socketcan interface with:

 sudo ip link set can0 type can bitrate 500000
 sudo ip link set up can0

you can run:

# Default Linux usage for Kia Soul EV
python3 oscc-check.py -V kia_soul_ev

Windows

On a Windows system socketcan is not available so the bustype and channel must be specified.

If you've installed the Kvaser SDK you need to run:

# Default Kvaser CANlib usage for Kia Soul Petrol
python oscc-check.py -c 0 -b kvaser -V kia_soul_petrol

Using PCAN drivers you can run:

# Default PEAK PCAN-USB usage for Kia Niro
python oscc-check.py -c PCAN_USBBUS1 -b pcan -V kia_niro

Running Tests

python3 setup.py test
