range of work undertaken by Keylevel Consultants Limited. Third party

Produce Specification and Test procedures for, and carry out
independent testing of, a high-integrity CAN gateway.
The gateway was to allow a development system to receive data from a
high-integrity CAN bus that could not tolerate disruption caused by
failures or errors within the development system. It was also required to
allow a limited set of messages to be sent from the development system to
the high-integrity system.
- Failsafe transceiver design for the high-integrity bus.
- Design of a fast software filter to be used when determining if an
identifier is to be routed from the development system to the high-integrity
system. The look-up time had to be less than 20us for any possible set of
identifier values.
- Failsafe database upload for software filter.
Jaguar Cars Limited
Design and implementation of an embedded Windows CE™ radar signal
processing node and associated data logging system.
- Windows CE™ kernel customisation work to integrate touch screen and TFT
LCD panel onto Hitachi SH4 platform.
- Windows CE™ application development to provide radar data collection,
signal processing and ethernet data logging stream generation at 50Hz update
rate.
- Windows 2000 application development to allow for logging of radar system
data and synchronous video capture (by means of Firewire and DirectShow).
Design and implementation of a Windows™ hosted data acquisition, signal
processing and replay software suite for automotive use.
- Windows NT™ device driver for 200mbps Hotlink™ interface to a high
specification automotive millimetre wave radar system.
- Video capture system to enable synchronous visible spectrum camera images
to be tagged to captured radar data.
- CAN interface to allow synchronous logging of vehicle dynamics and user
interface information.
- Real time environment to enable radar data signal processing and target
threat assessment to be carried out.
- Data capture to disk in real time, both continuously and event-triggered
(with pre- and post- trigger delays).
- Real time 3-D rendering of camera image, radar data, signal processing
output and threat assessment target selection using OpenGL™.
Design and implementation of real time software in 'C' for an Infineon C505C
based 'haptic' speed controller.
- Pulse width modulated road speed capture.
- PID controller for haptic throttle pedal actuator driver.
- User interface to allow 'intuitive' driver control of the system.
 European 4th Framework
Anti-Collision Autonomous And Safety Intervention System (AC-ASSIST) project.
- Advanced sensor system consisting of visible spectrum camera, millimetre wave radar and sensor fusion system allowing determination of road path and
obstacle detection for a vehicle based collision warning and intervention
system.
- Algorithm design and implementation in 'C' for an Infineon C167CR based
collision warning alarm designed to enable an inattentive or distracted
driver to react in a timely manner to a potentially hazardous situation.
- Algorithm design and implementation in 'C' for an Infineon C167CR based
collision intervention system designed to mitigate or prevent longitudinal
vehicle collisions by means of electronic throttle and brake control.
 European 4th Framework Urban Drive Control
(UDC) project.
- Roadside to
vehicle microwave telematic link providing traffic light phase and recommended
vehicle speed information to the driver to allow optimisation of traffic flow in
urban areas.
- Stop & Go system allowing the vehicles' speed to be automatically
controlled so as to maintain a safe following distance to the vehicle in
front. The system comprised of a millimetre wave radar, electronic throttle
controller, user interface, electronic brake control and micro-processor
based vehicle dynamics controller.
Various implementations in 'C' for Philips 82C592 based real time modules
with CAN interface.
- User interface with DMA sound generation, LCD interface, analog and
digital inputs, lamp driver outputs, charge pump driven fail-safe module and
a SLIO (software-less CAN node) input expansion module.
- Road speed input and actuator output node.
- Yaw rate input node.
- Hand held diagnostic interface.
Windows™ hosted RS-232 data logger for vehicle dynamics controller data
recording and system development.
Alpine of Europe
- Automotive road speed interface module for
in-car navigation system.
- Micro-processor based hardware and software design.
- CAN interface to vehicle for road speed determination.
- Variable frequency digital interface to enable road speed to be sent to
navigation system.
Motorola
