These features are related to, but not core to the upgrade to networked electrics.

  1. Upgrade Airconditioning.
    The system is blowing bits of foam insulation out of the vents. The insulation is disintegrating after 20 years of exposure to the elements and a minor coolant leak from a heat exchanger. A fix means removal of the heater box as well as air vents to replace the foam.
    While the unit is out of the car, the vaccuum-operated flaps will be changed to electric, based on central-locking master actuators for positional feedback. A servo-motor is to be fitted to the air blend flap. This facilitates, along with some trickery behind the temperature and ventilation control  panel, for a temperature to be set and for the air-blend control to adjust to maintain the set cabin temperature.
    A side benefit is that the recirculation control flap can automatically close when e.g. reversing or when the windscreen washer is run.
  2. Integrated central locking and dead-locking by separating the door lock buttons mechanically from the locks. The lock buttions are to operate a centre-off, momentary switch to lock and unlock doors. The front door lock buttons could e.g. provide for selective central locking and unlocking of all doors.
    Doors could also be locked automatically when a certain speed is passed and unlocked when the ignition is switched off.
    Replacing all vaccuum-operated lock actuators with “master” electric lock actuators provides for central locking and unlocking at both front doors via the key, as well as providing input to an immobiliser/alarm.
  3. The fuel pumps (which are at the back of the car) can be run for a short interval purging gases from the fuel rail and making for an easier start after the driver’s door is opened after unlocking by remote or key.
  4. Interior light delay can be programmed for an interval when a door has been opened, fading slowly at the end; fading quickly when the ignition is switched on; coming on for an interval if the parking or headlights are on and the engine stopped; switching off quickly when the doors are “double-locked” by key or remotely; and switching on for an interval when the car is unlocked by key or remotely.
  5. The rear wiper can be set to wipe (once) automatically if the main wipers are operating and reverse gear is selected.
  6. The front wiper motor may be opened to install an encoder onto the shaft instead of the cam and embed an H-bridge into the motor. Such a motor on each wiper arm would eliminate the wiper linkage by each motor driving a wiper arm directly. The motors would be electronically synchronised with each other. By positioning the passenger-side wiper arm to the outer hole, the arms could also sweep in a scissor action, parked in the centre of the screen, “on top” of each other. Wipers would then wipe to both A-pillars. Of course a wiper arm and blade would have to suit the “opposite” direction of operation.

These topics will migrate to sub-pages as the respective concepts develops.
