Thanks.

First of all, I would suggest you stick to RF control instead of IR.
IR, being line-of-sight, is very limited for RC car control.

Many RC cars are controlled with 2-channel PWM RF signal, one for
throttle and one for steering. If you google "hobby servo" you can
learn all about it. So you could hack into the transmitter that comes
with the car and control it at a low level with the CE box. I've
never done this. It would probably be challenging.

Us robot geeks would normally put a microcontroller with some smarts
on the car to command the throttle and steering, add some
environmental feedback sensors, and just send higher level commands
and data from/to the PC via RF (using something like Zigbee serial).
