E-bikes often come with a torque sensor in the crankset that feeds a signal to the motor controller where the user can then choose the amount of pedal assist they desire.
These systems can be/are overridden by a std electric bicycle brake style throttle that could easily be integrated with the std foot throttle control in a car.
IMHO this is the easiest method of getting a DIY electric assist system to work with a ICE powered vehicle.
The sticking point for me has been the lack of 'bolt on' torque sensor.
These guys seem to have all the bases covered:
- Engine
- Transmission
- Driveshaft
- Transfer case
- Differential

Amongst other things,
THE DRIVE SHAFT SYSTEM IS USED FOR:
- Evaluation of the aerodynamic efficiency of the vehicle
- The effectiveness of aerodynamic setup changes (e.g. roll-out tests, straight-ahead tests)
I hadn't considered that!
Then again, the supplier hasn't considered motor control.
