VEHICLE SIMULATOR

See the controller at work on a vehicle.

Drive the vehicle, then look at what the connected platform adds: diagnostics, analytics and over-the-air updates.

The controller reports its own health over the CAN bus, to Controller Suite or to the connected cluster.

Torque below the middle line is regeneration. Recovered share:

New firmware reaches the vehicle through its connected cluster and is passed to the controller over CAN.

Cluster downloads the update over the air
Vehicle confirmed stationary
Firmware transferred to the controller over CAN
Checksum verified
Controller restarts on the new firmware

In this illustration the update installs only once the vehicle has stopped.

This is an illustration of how the system behaves. The vehicles are generic examples, and the component positions, speeds and figures are not measured data. The Indian Driving Cycle scenario is modelled on the published cycle (108 seconds, a top speed of 42 km/h, an average of 21.9 km/h) and repeats until the vehicle has covered 1 km. Motor speed is calculated from vehicle speed, the wheel size and the drive ratio. The wheels turn at their true speed and blur as the vehicle speeds up.
