“…The steering demand in equation (11) was replaced by the integral of the tilt error term indicated by b in equation (14). Along with resolving the conflicts between the two control systems, this control strategy confirms azero steady-state tilting moment in the case of the vehicle parameters changing (e.g.…”

Traffic congestion, pollution due to vehicular emissions and fuel energy crises are the major problems that have inspired research for the design of efficient and smaller vehicles as a regular mode of transport with a significantly lower carbon footprint. With an increased dependency on certain countries for fuel energy, electric mobility has been encouraged by policy makers so that national interests are not compromised. At the same time, enhanced standards of living have resulted in a demand for safer and comfortable transport. All of these factors have led to a need for a mode of transport that is efficient, compact, safe and comfortable. Electric three-wheelers are seen as one of the promising options that fits all of these requirements. Due to their high propensity to rollover during cornering, however, the use of three-wheeled vehicles (3Ws) is limited to low-speed applications for cheap transport. Recent developments in the field of rollover mitigation through active tilt control mechanisms indicate that the future mode of transport will be more exciting than the existing one. This paper is a review mainly focused on the recent technological developments in active-tilt-controlled three-wheeled vehicles. This paper gives a detailed review of the methodologies chosen, control strategies adopted, types of vehicle chosen for test/simulation, mathematical models applied, key findings and future work proposed to address the dynamics-related issues of tilting 3Ws.

“…The rapid addition of new models in the 3W segment 10 and the escalation of sales is apparently indicative of the fact that 3Ws are becoming more popular with the growing traffic and manoeuvrability requirement on roads in recent times. [11][12][13] Recent developments in the 3W market…”

Many health, environmental, and quality-of-life benefits to cycling have been identified, including exercise, zero-emissions, reduced pavement requirements compared to cars and busses, and nearly silent operation. [1] There has also been a huge recent world-wide investment in infrastructure, including kilometers of lanes and paths, parking, bike share, and shower facilities at workplaces. [2] A significant fraction of the population, however, is unable to join in this activity with traditional upright bicycles, including people with balance or joint limitations caused by injury, disease, or age. [3] One solution to these ergonomic difficulties is the recumbent bicycle, but many riders find them difficult to balance and steer because of several factors, including centre of mass location and steering geometry. [4] Another solution, the recumbent tricycle, must have a wide axle track for lateral stability when turning, which requires more pavement and creates more aerodynamic drag than the bicycle equivalent. [4] Tilting tricycles can behave just like bicycles and so have the same handling issues or incorporate complicated and costly tilting actuation. [5][6] We present a solution that aims to combine the best attributes of all these vehicles and eliminate the drawbacks: a tilting tricycle with variable stability that the rider can control manually. By varying the centre of mass trajectory while tilting, it balances like a bicycle when going fast and so has lateral stability provided by tilting like a bicycle, and it balances like a tricycle when stopped or going slow to eliminate excessive steering burden on the rider. [7] It also requires no more pavement than a bicycle and has little more aerodynamic drag than a recumbent bicycle because of its narrow track.An additional beneficial side-effect of the variable tilting mechanism is that the seat can be higher when stable to facilitate getting in and out of it, and the seat can be lower when unstable to reduce frontal area and therefore aerodynamic drag.We present the titling linkage that implements this functionality, a mathematical model and the stability eigenvalues it produces, and confirmation of the model with a ridable physical prototype.
