What do we do?

Driveline Control software design development & integration. Vocis can offer complete design, development & integration of driveline control systems for any automated transmission system or active torque distribution axle system. Vocis has considerable experience in wet and dry DCTs, AMTs, planetary auto’s and other innovative transmission layouts and concepts. More than 30 vehicles for seven customers or OEMs are running with a complete Vocis control system included TCU and software. Vocis is increasingly involved in electric and hybrid vehicle activities and has completed several projects in this field. Vocis is continually investing in R & D to ensure it remains at the forefront of transmission controls.
Design & Integration of electrical & hydraulic control systems. Vocis is frequently involved in the design, development & integration of gear, clutch, park brake and differential clutch actuation systems, both electrical and hydraulic. Vocis have considerable experience in achieving a sound mechanical system integration to ensure the maximum system functional performance and fewest system compromises. Vocis can offer in house expertise and additional work with external specialists and tier 1 suppliers to define and engineer an appropriate solution for customer applications
TMS-20 Transmission Controller The Vocis TMS-20 transmission control unit, now in Mk 3 version, is available to enable customer and in house programmes to run production representative fixed point software on a variety of alternative target processors in a realistic and compact hardware platform. The TMS-20 has been a tremendous asset to many OEMs enabling early prototype transmissions to run either on rig or in vehicles well in advance of first prototype samples of the production hardware being available. This has on many occasions saved weeks or even months of development time and at very affordable price compared to other solutions. A high speed data logging version of the controller is also in use internally which we plan to make available in the future
Hardware in the Loop (HIL) testing to reduce costs & downtime Hardware in the loop is extensively used during software development to test software function in both an accelerated and risk free way. Vocis has invested heavily in an ETAS HiL system and has worked to develop extensive in house processes to speed up the entire software development process from initial system requirements capture through to final automated test.
Concept Engineering & Simulation Modelling Vocis offers initial concept engineering for transmission system layout and simulation modelling. Concept engineering covers the range from transmission layout and actuation system integration, transmission controller specification definition for third party manufacture, external world wiring interface definition, complete control system simulation and efficiency modelling. Vocis also has increasing links with various Universities and is collaborating with Surrey University on state of the art simulation and test rig correlation of EV driveline systems. Vocis can carry out complete programme management of transmission programmes for customers if required and has considerable experience in this area for both software and hardware based programmes.
Last Minute Engineering Vocis has on several occasions been brought in to resolve last minute pre SOP problems for some well known OEMs. This work has covered mechanical, hydraulic and software areas of modification and has enabled the customers to progress with their planned launch activities
Confidential & secure office/workshop & test track facilities. Vocis has a permanent and well equipped office and workshop facility at MIRA in the UK. www.MIRA.co.uk In addition to all the facilities at our disposal at MIRA, Vocis also has a dedicated transmission spin test rig and a dedicated cold test chamber. Customer and internal R & D programme vehicles can be and are kept securely at this facility and tested on the various tracks or on local roads if appropriate
Electric Vehicle Drive Systems Vocis is actively involved in this growing area of interest with close links to several OEMs and other key European specialist motor and battery suppliers. A significant in house joint Vocis Graziano 2 speed (patent pending) seamless shift transmission design is undergoing testing now and is expected to be in a collaborative project demonstrator vehicle later this year.
Mechanical Engineering/Design Gearbox design / Prototype build Vocis has already designed, arranged manufacture of a total of 4 separate complete transmission designs. In total of 18 actual units have been covered by these 4 programmes. The typical time frame from project kick off to first unit completion has been 12 – 16 weeks. Quality Vocis achieved ISO 9001 and TickIT accreditation in early 2009.
