MIPI moves into automotive

By Nick Flaherty at

The MIPI Alliance,has formed an Automotive 'Birds of a Feather' (BoF) Group to get industry input from original equipment manufacturers (OEMs) and their suppliers to enhance existing or develop new interface specifications for automotive applications. 

The group is open to both MIPI Alliance member and non-member companies to represent the broader automotive ecosystem.

While MIPI stared out developing interface specifications for mobile and mobile-influenced industries, cars have become a new platform for innovation, and manufacturers are already using MIPI Alliance specifications as they develop and implement applications for passive and active safety, infotainment and advanced driver assistance systems (ADAS). 

MIPI interfaces such as Camera Serial Interface 2 (MIPI CSI-2), Display Serial Interface (MIPI DSI) and Display Serial Interface 2 (MIPI DSI-2) are used for a variety of low- and high-bandwidth applications that integrate components such as cameras, displays, biometric readers, microphones and accelerometers. MIPI I3C helps automotive systems designers use multiple sensors in a space-constrained form factor. Highly sensitive, mission-critical automotive applications also benefit from MIPI interfaces' low electromagnetic interference (EMI).

However interfaces such as MIPI CSI are designed for short distance links in cell phones up to 30cm, The Automotive BoF Group's initial focus will be to examine how MIPI specifications can potentially be extended to support communication link distances up to 15m, and at the same time support the high data rates associated with cameras and radar sensors for autonomous driving systems.

"Automakers already rely on MIPI Alliance's industry-standard interfaces to enable a wide variety of applications, including collision mitigation and avoidance, infotainment and navigation," said Matt Ronning, chair of the MIPI Alliance Automotive Subgroup and the Automotive BoF. "This call for participation helps ensure we cast a wide net to capture expertise to aid with extending existing and shape future MIPI specifications and collectively help realise the vision of how connected cars and automotive applications will evolve over the next decade. Just as mobile handset manufacturers benefited from the standardisation that MIPI Alliance has provided, automotive OEMs would similarly benefit."

"Active participation of automotive OEMs, tier-one and tier-two suppliers is greatly appreciated and necessary to, for example, work out the data link requirements between surround sensors, electronic control units, actors and displays for driver assistance and autonomous driving projects beyond 2020 and incorporate them into MIPI interface specifications," said Uwe Beutnagel-Buchner, vice chair of the MIPI Alliance Automotive Subgroup and the Automotive BoF.

The MIPI Automotive BoF is seeking additional qualified experts from OEMs, tier-one suppliers, component suppliers and related companies to provide key input into current and future MIPI interface specifications. The Automotive BoF is expected to convene via teleconference on a biweekly basis, with face-to-face meetings planned as necessary.

Companies already participating in MIPI Alliance’s Automotive BoF Group include: Analog Devices; Analogix Semiconductor; BitSim; BMW; Cadence Design Systems; Continental; Etron Technology; Ford; Microchip Technology; Mobileye, an Intel Company; NVIDIA; NXP Semiconductors; ON Semiconductor; Parade Technologies; Qualcomm; Robert Bosch; Sony; STMicroelectronics; Synopsys; TE Connectivity; Tektronix; Teledyne LeCroy; Texas Instruments; Toshiba; Western Digital and others.
